Estuary Ecosystem

...Abstract Normally found along coastal lines, estuaries offer a safe haven for water, air and land creatures alike. One flourishing estuary in particular is located in the Tampa area and is known as the Tampa Bay Estuary. The Nitrogen cycle is a cycle where nitrogen through decaying vegetation, excrement and carcasses materialize into the nitrogen we find in the soil. The Nitrogen cycle is almost identical to the Carbon cycle. Natural Disturbance are disturbances caused by Mother Nature. Anthropogenic caused disturbances are man’s way of harming the ecosystem. Nature has a way of recovering with and without help. Estuary Ecosystem The United States of American is a country that consists of many different ecosystems in a relatively small space. From the arid desert climate with scorching temperatures to mountainous areas that stay frozen year round, the United States has many different ecosystems to offer. One ecosystem in particular is the estuary system. Normally found along coastal lines, estuaries offer a safe haven for water, air and land creatures alike. It also offers a great area for many different types of vegetation to grow. One state with a plethora of estuaries is the state of Florida. Florida, having a relatively warm climate year round and having a coast line that almost surrounds the entire state, gives these ecosystems a great environment to flourish. One flourishing estuary in particular is located in the Tampa area and is known as the Tampa Bay Estuary. This...

...A pollutant can affect the health of humans, as well as the health of plants and animals. Pollutants can also affect non-living materials such as paints, metals, and fabrics. The video also talked about “The Carbon Cycle” which is a complex series of processes through which all of the carbon atoms in existence rotate. The same carbon atoms in your body today have been used in countless other molecules since time began. The wood burned just a few decades ago could have produced carbon dioxide which through photosynthesis became part of a plant. Secondary pollutants are generally more problematic than that of primary pollutants, because mitigation of secondary pollutants requires the identification of the precursor compounds.. The video also talks about using an “AQI” which is an index for reporting daily air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. To make it easier to understand, the AQI is divided into six categories. The six levels of health concern and what they mean are: “Good" AQI is 0 - 50. Air quality is considered satisfactory, and air pollution poses little or no risk, "Moderate" AQI is 51 - 100. Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people. For example, people who are unusually sensitive to ozone may experience respiratory symptoms; “Unhealthy for Sensitive Groups" AQI is 101 - 150. Although general public...

...to travel on which in turn leads to more waste being put into the air by those vehicles. Discuss 2 reasons why this is very difficult, especially in the Amazon Tropical Rain Forest. 3) A. The biggest reason is because of the over population of the world. They needs to be more land to build houses and communities for people. B. Another reason is because there are so many more people I the world, there needs to be more food. Since the Amazon is such a large area of land it just continues to get cut down for more places to plant plantations. Not only that but we also need the wood for furniture and paper products for everyone. Looking at the Water & Carbon Cycle (chapters 3 & 10), discuss how deforestation impacts these two cycles. 4) Trees are extremely important to the water and carbon cycles. Firstly they absorb rainfall and produce water vapor that is released into the atmosphere. The biggest advantage of this is that it prevents widespread flooding.

...ENV 122 Lab 04: Habitable Planet Carbon Cycle This lab is developed from the Habitable Planet Interactive Carbon Lab found at https://www.learner.org/courses/envsci/interactives/carbon/ Overview This lab uses a robust model of the carbon cycle to give you an intuitive sense for how carbon circulates through the atmosphere, biosphere, oceans, and crust. This model is similar to ones presented by the Intergovernmental Panel on Climate Change (IPCC). It allows you to experiment with how human input to the cycle might change global outcomes to the year 2100 and beyond. One particularly relevant human impact is the increase in atmospheric CO2 levels. Between the years 1850 and 2015, atmospheric concentrations have risen from 290 parts per million (ppm) to over 400 ppm - a level higher than any known on Earth in more than 30 million years (see Unit 12 to find out how scientists measure ancient atmospheric carbon levels). Using the simulator, you will experiment with the human factors that contribute to this rise and explore how different inputs to the carbon cycle might affect the concentrations of the greenhouse gas CO2. Procedure Read through the material and follow the directions provided on the Habitable Planet website (unless otherwise instructed). Fill in the tables below with your data and answer the questions. Note: DO NOT download the data tables provided on the HP website. This file contains everything you will need. Save your file as: LASTNAME-Lab04-HPCarbonCycle...

Yeast Culture Lab

...Yeast Culture Lab Introduction Yeast is a one-celled, microscopic organism, which is part of the fungi kingdom. Yeasts do not make up a single group (Smith & Smith, 2012). Yeasts use organic material as a means of making energy, which make them chemoorganotrophs (Smith & Smith, 2012). Carbon is procured primarily from hexose sugars, such as fructose and glucose. Yeast need either oxygen for aerobic cellular respiration or for species that are anaerobic, but also have aerobic methods creating energy (Smith & Smith, 2012). There are no species of yeast species that are known to grow only anaerobically. Yeasts thrive in an environment with a slightly acidic (Smith & Smith, 2012). The reproductive cycle of yeasts can be either asexual or sexual depending on the species. The most widely seen method of growth in yeast is asexual reproduction referred to as budding (Smith & Smith, 2012). Reproduction in reference to yeast depends on the species; the species can be both asexual by mitosis and sexual by budding (Smith & Smith, 2012). Consumption refers to use and the rate of use of something such as how a consumer, such as a primary consumer like a tree would use photosynthesis to make energy from carbon dioxide. Death in reference to a population is referring to the rate of death in that population (Smith & Smith, 2012). Hypothesis The primary goal of the yeast culture lab is to test a theory involving samples of yeast cultures grown...

Photosynthesis

...Photosynthesis Pre Lab Questions Joey Gramenzi 11/11/15 Period: 2 1. How can the rate of photosynthesis be measured? You measure the amount of oxygen produced, or the amount of carbon dioxide used. If the rate of photosynthesis increases, so does the amount of oxygen and Carbon Dioxide used. 2. Where in the cells of the leaf do you find air spaces? What is the function of the stoma? In the cells of the leaf, you find air spaces where the stoma is located. The stoma allows for carbon dioxide to come in, and oxygen to go out. 3. What will happen if you remove the air from these spaces? The leaves will sink because they become more dense than water and cannot carry out photosynthesis. 4. How will air return to these spaces? The stoma opens up when it requires more Carbon Dioxide, and once its enriched with it, oxygen will exit the stoma at the end of photosynthesis in the Calvin Cycle. 5. Instead of carbon dioxide, what will be used as the reactant in this lab? The leaf will be placed in a solution of bicarbonate ions, rather than carbon dioxide. 6. List any factors that you think may affect the rate of photosynthesis. Consider environmental factors that you could manipulate during the lab. * Limiting the amount of Carbon Dioxide * Too much water could ruin the plant * In a place where there is little to no sunlight 7. Watch the video that shows the set-up for the floating leaf disk lab at Bozeman Science. a) What is the ratio...
