Modeling the Carbon Cycle For this assignment, you will develop a scientific model on a poster that illustrates the role of photosynthesis and cellular respiration in the carbon cycle. Your model should also show how carbon cycles the Earth’s four spheres. Once you have completed your model, you will write a paper with several paragraphs describing the content of your model in more detail.
1) Create a model of the carbon cycle showing how carbon cycles through an ecosystem.
i. Show photosynthesis and cellular respiration contributing to the carbon cycle.
ii. Depict the movement of carbon through the atmosphere, hydrosphere, biosphere, and geosphere.
iii. Include the role of fossil fuels and fossil fuel emissions in the carbon cycle. You may have to do additional research to find out where fossil fuels come from and where they are stored.
iv. Represent the diffusion of carbon dioxide in oceans. You may have to do additional research to find out where this carbon dioxide comes from and what happens to it in the ocean.
b) Draw arrows indicating how carbon moves within and between both living and nonliving parts of the environment.
2)Type several paragraphs describing the full carbon cycle in detail.
i. Discuss all components of your poster, as outlined in step 3.
ii. Describe the exchange of carbon through carbon-containing compounds between an organism and the environment.
iii. Describe the contributions of photosynthesis and cellular respiration within and among the four spheres. Discuss how carbon enters and leaves each of the four spheres and in what forms.
iv. Discuss the role of carbon storage in organisms.
i. How is a model of the carbon cycle different from the actual cycling of carbon in an ecosystem?
