Extinction is a natural selection process. Should humans strive to preserve a representative sample of all biomes or aquatic zones? Why should humans be concerned with the extinction rate? at least 150 words in length. Support your claims with at least two references to support of your position. Cite your sources.
“Many anthropologists postulate that as Paleolithic people migrated to new lands with advanced hunting technologies, they hunted existing large animals to extinction, creating the first human-caused environmental catastrophe.” (Turk, J., & Bensel, T.2011) Human’s area species. We directly depend on thousands of other species for our survival, and each of them depends on thousands of others, and each of them depends on thousands of others, and so on.

An extinction "event" occurs when the collapse of one species leads to the collapse of others. Evidence suggests that several "mass extinction events" have happened in the past that wiped out half or more of all of the species living at the time. We may be witnessing the start of another mass extinction right now.

We don't fully understand the "web of life" upon which we depend for our existence. What would you do, if you depended on something you didn't understand to keep you alive, and one day, you noticed that it was changing into something else? Would you try to stop it from changing? or would you just wait to see what happens next?
Extinction is a natural selection process. However anthropogenic impact has increased the rate of extinction far beyond what is considered natural, and thus humans should be concerned with the extinction rate. Humans should strive to preserve a representative sample of all biomes and aquatic zones.
“Aquatic biomes marine and freshwater cover three-quarters of the Earth’s surface and include rivers, lakes, coral reefs, estuaries, and open ocean.” (Turk, J., & Bensel, T.2011)The world’s marine ecosystems account for 80% of animal diversity and provide not only aesthetics and recreational uses, but also a main food source for many cultures. Additionally, scientists are discovering that many of the ocean’s natural products can be used for medicinal purposes and may even be able to help cure cancer. Sea sponges possess certain substances that are used in chemotherapy for leukemia and lymphoma. As our oceans become degraded, natural organisms such as sea sponges that provide beauty along with healing properties diminish, and thus the quality of human life lessons.
Coral reefs are one of the most biodiverse systems that scientists are trying to conserve before it goes extinct. Coral reef animals and substrates offer a variety of different substances that be used in cancer therapy. If coral reef ecosystems are lost, we will lose a biome that provides fish for food, medicine for healing, and beauty for recreational purposes. Thus we must try to save it and use it in a responsible manner. on 12 Aug 2012

Marine Biomes

...Marine Biomes Shonda Morton October 20, 2013 SCI/230 Paula Roberts A marine biome is a large aquatic zone that takes up almost 75% of Earth’s surface, has a salt concentration around 3%, and is distinguished from other biomes by its physical environment. According to Campbell Essential Biology with Physiology, (2010), the habitats of a marine biome varies depending on the level of the sea that it exists (pp.382). The layers or “zones” that make up the marine biome consist of the pelagic realm, the intertidal zone, the photic zone, the aphotic zone, and the benthic realm. The pelagic realm is the part of the marine biome that includes all open water. (Dickey, Reece, & Simon, 2010) explains “the intertidal zone is the part where the ocean surface meets land, or fresh water (pp.383).” The level of the marine biome is home to sedentary organisms such as algae, mussels, and barnacles. The photic zone was named mainly because of the fact that light is available for photosynthesis, and known as the upper or shallow layer of the marine biome. In Campbell Essential Biology with Physiology, (2010), the aphotic zone is the layer of the marine biome where the light levels are too low to support photosynthesis (pp.380). The benthic realm which exists in all aquatic biomes is the area of the seafloor, made up of sand, and organic and inorganic sediments. There are many organisms that exist in a marine biome, and each one exists at different......

...------------------------------------------------- Freshwater ecosystem From Wikipedia, the free encyclopedia Freshwater angelfish Freshwater ecosystems are a subset of Earth's aquatic ecosystems. They include lakes and ponds, rivers, streams, springs, and wetlands. They can be contrasted with marine ecosystems, which have a larger salt content. Freshwater habitats can be classified by different factors, including temperature, light penetration, and vegetation. Freshwater ecosystems can be divided into lentic ecosystems (still water) andlotic ecosystems (flowing water). Limnology (and its branch freshwater biology) is a study about freshwater ecosystems. It is a part of hydrobiology. Original efforts to understand and monitor freshwater ecosystems were spurred on by threats to human health (ex. Cholera outbreaks due to sewage contamination). Early monitoring focussed on chemical indicators, then bacteria, and finally algae, fungi and protozoa. A new type of monitoring involves differing groups of organisms (macroinvertebrates, macrophytes and fish) and the stream conditions associated with them. Current biomonitering techniques focus mainly on community structure or biochemical oxygen demand. Responses are measured by behavioural changes, altered rates of growth, reproduction or mortality. Macroinvertebrates are most often used in these models because of well known taxonomy, ease of collection, sensitivity to a range of stressors, and their overall value to the......

Explain The Stages Of Succession

...Terrestrial Ecosystems Tundra is a treeless biome occurring in areas with cold climates and a short growing season. Alpine tundra occurs at high altitudes on mountains, while arctic tundra occurs at high latitudes. Most tundra receives a very small amount of water as precipitation , but nevertheless their soil may be moist or wet. Boreal forests are cold, conifer dominated forests covering large portions of Europe, Asia, and North America. They have short damp summers; long, cold winters; and short growing seasons.Their thin soil is acidic and nutriently poor. Precipitation mostly comes in the form of snow and is roughly equivalent to 16 to 40 inches of rain a year. Animals inhabiting the boreal forest include weasels, woodpeckers, hawks, moose, bear, squirrels, fox and bats. The tropical rainforest biome is an ecosystem that covers 7% of the earth’s surface. They are found all over the world but the majority of the tropical rainforest lies in south america in brazil.The average temperature of the tropical rainforest remains between 70 and 85 degrees F. The tropical rainforest is very rainy. Most of the animals living in the tropical rainforest live in the trees. There they can find all of their necessities and rarely have to come down to the floor. Because of the amount of trees in the tropical rainforest biome, it is responsible for the majority of oxygen production in the air that we breathe. Coniferous forest is a kind of biome situated in temperature......

...Homework #1 – Basic Terms and Concepts Name: Intro to the Environment - Eco Footprint - Homework #1 (HW1) – Fall 2012 1. An ecosystem is a community of organisms living in a particular environment and also the physical elements in that given environment, in which these organisms interact. Its diversity is profoundly substantial. An ecosystem can extend from the icy artic zones to the tropical forests. They occur in many different scales with smaller systems pierced inside larger systems. Depending on the scale, an ecosystem can be small or profoundly large. 2. Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. In plants, photosynthesis generally involves the green pigment chlorophyll and generates oxygen as a byproduct. 3. A producer in an ecosystem, converts energy from the environment into carbon bonds. For instance, green plants use energy from the sun to create more complex molecules like carbon dioxide into glucose. Consumers on the other hand are organisms that obtain nutrients from other organisms. They attain their energy from the carbon bonds made by the producers. An example of a consumer is animal that gets its energy from plants. It is also called an herbivore. A few examples of herbivores include cows, moose, gazelles, rabbits and elephants. The trophic level of an organism is where the organism is situated in the food chain. A food chain is similar......

Natural Resources and Energy Paper

...Natural Resources and Energy Paper A forest is a natural resource needed by the earth, humans, and species. There are three types of forests. The three types include “tropical, temperate, boreal forests” (The forest biome p. 1, 2006). Recently forests occupy about “one-third of Earth’s land area, and account for over two-thirds of the leaf area of land plants, and contain about 70% of carbon present in living things” (The forest biome p. 1, 2006). Forests produce vital oxygen and provide homes for people and wildlife. Forests play a critical role in mitigating climate change. A forest have several management practices for sustainability and conservation. There are several risks and benefits of extracting and using one type of nonrenewable and one type of renewable energy. The growth of human population has affected forest resources in several ways. The affected forests have caused harm to the population of wild species and have majorly impacted agriculture. Impacts associated with agriculture Between 2000 and 2010 about 13 million hectares of forests were lost per year to agriculture and other uses (Food and Agriculture Organization of the United Nations, 2013). Agroecosystems are very different from the ecosystems seen in nature. Unlike natural ecosystems, agroecosystems are large areas that have been planted with a single species or single strain or subspecies. This often makes them more susceptible to disease. Also, the agroecosystems are often planted in simple......

The Biological Model of Human Development

...emissions affecting the earth’s climate. Human acts such as; burning fossil fuels and energy for deforestation is large contributors to an increase in green house gases. Humans are pouring carbon dioxide (CO2) in to the atmosphere much faster than plants and oceans can absorb it. This has been going on for years and because of the build up of emissions, it is impossible to prevent global warming. Deforestation Deforestation causes extinction in certain species. Humans are a species and we depend on other species for our survival. Land use directly leads to species extinction (Turk, J & Bensel T 2011 chapter 4). Humans should reserve biomes and aquatic zones because life is dependent upon it. An interruption to these zones causes a depleting effect creating irreversible lose of important organisms.

Ap Bio Ecology Take Home Yesy

...James Shin Per 7b/8 Ecology Take Home Test 1) In the given info, there were two groups, an experimental and control group of flowers and sagebrush in a desert landscape that were identical except that the experimental group had a fence enclosed around it. Also, there was a predation relationship between the wildflowers and the kangaroo rats because the kangaroo rats eat wildflowers. Assuming that the fence was limiting the space of the experimental plot, competitive exclusion caused the extinction of the 4 other wild flowers. To begin, there was some interspecific competition, which happens when individuals of different species compete for a resource that limits their survival, between the 5 flower species in the experimental plot because they had their space limited to the fence that they were enclosed in. this competition was a density dependent factor in that the death rate rose when population density in the plot rose. Also, some of the specie’s ecological niches (like what nutrients they needed and how many branches would form) would have had to been the same or else they could coexist together. Then, one of the species of wildflower might have had a reproductive advantage like thorns to repel the kangaroo rats which would have allowed them to prosper and the other species to die out. This is the principle of competitive exclusion. On a tangent, the kangaroo rats would have learned to stay away from the wildflower with thorns by classical conditioning because they...

...The Arctic and subarctic regions Compared with other biomes, the tundra biome is relatively young, having its origin in the Pleistocene (1,600,000 to 10,000 years ago). Individual plant and animal species of the tundra, however, probably first appeared in the Late Miocene (11.2 to 5.3 million years ago) or Early Pliocene (5.3 to 3.4 million years ago). Coniferous forests were present on Ellesmere Island and in northern Greenland, the northernmost land areas, in the mid-Pliocene (2.5 million years ago). Most paleoecologists believe that tundra flora evolved from plants of the coniferous forests and alpine areas as continents drifted into higher and cooler latitudes during the Miocene (23.7 to 5.3 million years ago). The Antarctic region Antarctica has been isolated from other continental landmasses by broad expanses of ocean since early in the Tertiary Period, about 60 to 40 million years ago. Prior to its separation it existed, along with Australia, South America, peninsular India, and Africa, as part of the landmass known as Gondwanaland. This long separation has impeded the establishment and development of land-based flora and fauna in the Antarctic. Other significant factors that have hampered terrestrial biotic evolution are the harsh climate, the ice cover that completely engulfed the continent during the Pleistocene glaciations, and the present limited number of ice-free land areas, which are restricted primarily to the coastal fringes and nunataks (mountain peaks......

Bottle Life Cycle

...The phosphorus cycle is the slowest one of the matter cycles. Phosphorus cycles through plants and animals much faster than it does through rocks and sediments. When animals and plants die, phosphates will return to the soils or oceans again during decay. After that, phosphorus will end up in sediments or rock formations again, remaining there for millions of years. Eventually, phosphorus is released again through weathering and the cycle starts over. Biodiversity is the variety of different types of life found on the Earth and the variations within species. It is a measure of the variety of organisms present in different ecosystems (Farabee). This can refer to genetic variation, ecosystem variation, or species variation within an area, biome, or planet. The main reason why biodiversity is so important is that it makes ecosystems so resilient to change. Human behavior impacts biodiversity in many ways. The permanent destruction of forests or deforestation is one of the most obvious impacts. One of the more immediate impacts that humans have is by introducing nonnative species and overharvesting. What is population? A population is group of individuals of the same species living in the same geographic area (Farabee). In brief I will discuss the population growth model. There are two modes of population growth, the Exponential and Logistic curve. Exponential curve occurs when there is no limit to population size, where the Logistic curve shows the effect of a limiting factor.......
