...population due to factors which can be categorised into the following: • Biotic factors –living components of an ecosystem • Abiotic factors-non-living components of an ecosystem e.g. rainfall Giving example, I will describe the effects biotic and abiotic factors will have on the dynamic equilibrium of populations. As previously defined, abiotic factors are non-living components of an ecosystem, which include temperature. For instance, the reproduction of the Leather back turtle is affected by rising temperature of the beach sand, in which it lays its eggs. This increase in temperature causes dramatic imbalances in the sex ratios of hatchlings. This will affect the dynamic equilibrium of the population as the imbalance in sex ratio could cause birth rate to decline, as individuals are unable to find a mate due to the imbalance. Another abiotic factor is PH of soil or water. For instance, clownfish are greatly affected by a decrease in PH in ocean water (oceanic acidification). This change in PH affects their sense of smell thus impede their ability to search for the sea anemones in which they live and depend for protection from predators. This will likely lead to an increase of death rate as clownfish will be unable to find a suitable habitat and unable to hide safely from predators. Therefore showing that the PH of water can affect the population’s dynamic equilibrium. Additionally, another type of abiotic factor is pollution. Pollution can come in many forms, such as air, water...

...which locale, physical, and chemical factors play a major role in the make-up of the biotic and abiotic environment. They can range from ponds, forests, estuaries, or grasslands. Some ecosystems are more complex than others depending on where they are located. Some have similar characteristics and some are different in many ways such as the abiotic and biotic components or the region it is located in. Grasslands for example have different names because of the region they are located, for example, grasslands known as prairies are located in the United States. There are two types of grasslands, temperate and tropical. Grasslands in the United States are temperate and typically found in the mid-west. The grasslands known as prairies are more useful to humans agriculturally due to them having two seasons. These grasslands get between 10 to 30 inches of rain per year which is good for vegetation purposes. That is known as a grasslands growing season. When the weather starts to get cold and dry, that is known as the grasslands dormant season which is when nothing grows and the grasses and plants start to die. Many of the grasslands in North America have been turned into farmlands. Grasslands have many abiotic and biotic components. Abiotic components are non-living things that affect the ecosystem. These components are sunlight, water, heat, temperature, climate, and nutrients in the soil. Biotic components are living organisms or things that affect the ecosystem. These components...

...Faulkner AIU Online Environmental Science Laura Stepp March 25, 2012 Abstract This article focuses on the rainforest’s and its structure, both biotic and abiotic and the the cycles that gives us the ability to live on this Earth. There are a several different types of biomes that cover the vast surface of our planet, but one in particular is very important. The Tropical Rainforest can be described as a forest of tall trees that is located in areas that receive year-round warmth. 50 to 250 inches of rain fall on these areas on average and almost all Rain Forest are located in the equator region. Tropical Rainforest are extremely important because of the oxygen that they provide to our planet, about 40% and the types of plants that have cured diseases and have helped fight ailments. Sadly, only about 6% remains of the world’s tropical forest due to deforestation (Rainforestsos.org, 2012) Scientists estimate that over half of the world’s species inhabit the Rain Forest and this is why it is so import that this biome remains intact and preserved. The Amazon Rain Forest and the Rainforests in Costa Rica are examples of the biome that shelter thousands of plan t and animals species that have just as much of a right to be on Earth as we do. The structure of the Tropical Rainforest has many layer that shelter both biotic and abiotic forms. The emergent layer is at the very top, even above the canopy and is home to birds, insects, snakes and monkeys. The next layer is the canopy...

...regions and can be gathered into six groups. You have moderate grasslands, flooded grasslands, xeric and desert grasslands, and tropical and subtropical grasslands that can all be assembled into classes. (Webkil Designs copyright 2012) The abiotic and biotic factors of the grassland are contributory in determining the structure and purpose of the ecosystem. The different abiotic and biotic factors work differently in different types of grassland ecosystems conferring to their environmental conditions. The Abiotic and biotic factors play a main part in the existence of the grassland ecosystem. (Webkil Designs copyright 2012) The abiotic aspects of grassland basically consist of the climate. Climate is one of the most significant abiotic factors that form the ecosystem and includes rainfall, temperature, wind flow, ground moisture and more. Natural grasslands have a precipitation of 500mm – 900mm per year. The deserts have anywhere between 250mm a year. This type of rainfall preserves the moisture and cooperates with the abiotic and biotic factors of the grassland. Grasslands can also happen in high rainfall areas. Grassland climates array from cool to hot summers, and ice in the winter in high autonomies. (Webkil Designs copyright 2012) The biotic issues of grasslands ecosystem includes the autotrophs and the heterotrophs which is the producers, primary consumers, secondary consumers and tertiary consumers. The primary producers contain the autotrophs that can photosynthesize and...

...affect the other. There is a component called abiotic and biotic. Plants and animal and also people are part of the ecosystem. An ecosystem means ecological system. Each organism has its niche. Plants are important or other animal. We are part of an ecosystem. Plants are important to animal that eats plant. It is because the animal gets energy from plant. Animal are not the only that is there it’s also people. People are also part of ecosystem. People are everywhere when you walk on the street, when you go to the park too. Something part of the ecosystem can also be underwater too. If you take away one thing it affects the other. For example, if you take away the plants it will affect the animals that eat plant; also, the plant eater would be extinct. Also the carnivores would be extinct. It is like if you take away one stick from under, it will pull the others. It’s also like how you take the leg from the table the whole table won’t be straight. Abiotic components are sunlight, temperature, precipitation, soil or water chemistry, etc. The biotic components are primary producer, herbivores, carnivores, omnivores, detritivores, etc. In conclusion, an ecosystem is a living thing. It has a community with animal that interact with other people in an environment. Everyone is in it. People animal and plant are part of an ecosystem. If anything is taken away it will affect the other. Also the component in the ecosystem abiotic and biotic. So next time when someone ask you what you...

...much longer to aid with steering and the front legs are used for grasping prey. The water strider lays eggs on the edge of water on rocks or aquatic plants. These insects eat other insects no matter if they are dead or alive. They have sucking mouth used to eat either terrestrial insects that have accidentally fallen on the water’s surface or other aquatic insects like mosquito larvae as it comes to the surface (National Wildlife Federation, 1996-2013). There are several factors that can change the stability and growth of this insect’s reproduction and population growth. Abiotic factors like water, temperature, and light can change the population but biotic factors like plants or other organisms can alter it also. If change within an environment happens then change to the organisms within the environment will happen as well (Elzinga, 2004). Abiotic Factors Abiotic factors are non- living components like water, temperature, and light. A rapid increase or decrease in any of these factors would have an effect on this species. Water is important to the water strider population because it is here that it lives and obtains its...

...Phase 1 Individual Project SCI201-1403A-12 Environmental Science and Sustainability July 10, 2014 Trena Woolridge Just to keep the theme going from the discussion board 2 assignment I decided to research and write about the Tropical Rainforest. I have always found the world’s rainforests to be very interesting with all of their secrets they hold inside of them. By doing this paper it will allow me to discover more in-depth information on the Tropical Rainforests. I wonder what all I will discover? There are many rainforests in the world but can be found only in three major geographical areas around the world. The one that stands out the most to me is the Tropical Rainforest in Central America in the Amazon Basin from the previous assignment I researched. Others are located in Africa, Australia, and Assam to name a few. Tropical Rainforests are made up of large trees, exotic wildlife, and thousands of species of plants. The structure of the Tropical Rainforest is very complex but can be simple to understand when broken down into sections. The rainforest can be divided into layers from top to bottom and can get a better understanding of the Tropical Rainforest as a whole. The different layers are: emergent, the canopy, the understory, and the leaf litter or cryptoshere or also known as the ground. Emergent are the larger, taller trees that stick out above the canopy. They can be 20-100 feet above the canopy and endures strong winds, temperature fluctuations, and damaging...

...Animals all have their own habitat and must learn to adapt to it. One of those animals is the Dumbo Octopus also known as Grimpoteuthis. The Dumbo octopus must learn to adapt to its biome and the biotic/abiotic elements in it. The Grimpoteuthis is a fascinating and rare to see because they live so deep in the ocean. The Dumbo octopus lives in a certain depth of the ocean and that zone is called the Abyssopelagic zone. The Abyss is very deep and can vary from 4,000 meters to 6,000 meters. The Abyss is near freezing and is totally dark. The Abyss has strong animals that are astonishing because they need to survive the climate, and the darkness. They also need to adapt to the water pressure because the Abyss is so deep. The average temperature...

...grasslands have an average of 10 to 30 inches of rain per year, have shorter grass, and have a growing and dormant season (Grasslands Terrain of Many Names). There are the Great Plains in the United States that cover from parts of Texas, New Mexico, Oklahoma, Colorado, Wyoming and Montana and covers all of Kansas, Nebraska, South and North Dakota, and covers all the way up into parts of Canada. In Africa there is the African Savanna, which is a tropical grassland that covers 25 territories and South Africa. The abiotic structure of grasslands includes the climate; rainfall, temperature, wind flow, and ground moisture. The bedrock has an influence on the type of soil and what can and cannot be grown in that location, slopes and elevation, floods, fires, high temperatures and freezing temperatures are also abiotic structures. The biotic structures include any living thing in that ecosystem. Grass, rabbits, moles, elk, snakes, birds, bacteria and fungi are part of the biotic structures (tutorvista.com 2014). You cannot have one with out the other in an ecosystem. The grass needs the rain as well as the animals in order to survive. The temperatures help decide which type of animals and plant life will live in that area as well. Carbon function in the ecosystem is to be used by the plants for photosynthesis and to make organic molecules (Slideshare.net 2012). It is pulled from the atmosphere and used to become stored food. Animals eat the plants and then their digestive system breaks...

...The Ecosystem of the Rainforest An ecosystem is a relationship among the living and non-living organisms in a designated area and the environment in which they interact with. It includes plants, trees, animals, water, and soil. The rainforest ecosystem includes a variety of species, plants, and animals. All living organisms in this ecosystem physically adapt to the rain. The climate in the rainforest is very humid due the amount of rainfall. A tropical rainforest is very hot and wet; this type of climate is hit directly by the sun because of its location near the equator. The closer you are to the equator the solar radiation there is. The average temperature reaches about 77 degrees Fahrenheit. This climates temperature remains about the same all year never dropping below 64 degrees Rain falls at about 250 cm each year. Because the sun is directly hitting the rainforest, when the sun warms the ground and sea the water evaporates into the air. Warm air vapor and cold ail vapor form eventually causing clouds to form resulting to rain. This water cycle constantly repeats itself. Rain occurs more than 90 days a year in a rainforest. The rainforest consist of mainly trees and animals, trees can reach up to 164 feet in height. Because of the climate plants such as ferns and mosses or epiphytes, receive lots of water and direct sunlight so they grow very tall. Along with the many species of plants living in the rainforest, tropical animals such as Toucans, anacondas...
