PLEASE HURRY 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. Background Information Earth is composed of four open systems that work together—the atmosphere, the hydrosphere, the biosphere, and the geosphere. The atmosphere refers to all air around you as well as the air that extends from the surface of the Earth into space. The hydrosphere refers to Earth’s water; this includes oceans, lakes, glaciers, rivers, streams, and groundwater. The biosphere refers to all organisms on Earth, whether they live in air, on land, or in water. The geosphere refers to the Earth’s interior, rocks, minerals, landforms, and processes that shape the Earth’s surface. Carbon is one of the six elements that are common to all living things. It is the basis for all life on Earth. Carbon moves through both living and nonliving parts of an ecosystem in an endless cycle called the carbon cycle.
Step 3: Create a model of the carbon cycle.
a) 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.
c) Include short phrases on your poster that summarize what occurs at each stage of the carbon cycle.
Step 4: Create a typewritten paper describing the carbon cycle.
a) 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.
b) Click “Enter” on your keyboard a few times to leave enough space to answer the following question.
i. How is a model of the carbon cycle different from the actual cycling of carbon in an ecosystem?
c) Make sure your paragraphs include correct sentence structure, punctuation, grammar, and spelling.
Step 5: Evaluate your project using this checklist.
If you can check each box below, you are ready to submit your project.
Did your poster show the contributions of photosynthesis and cellular respiration to the carbon
cycle?
Did your poster depict the movement of carbon through the atmosphere, hydrosphere, biosphere, and geosphere?
Did you include the roles of fossil fuels and fossil fuel emissions in the carbon cycle?
Did you represent the diffusion of carbon dioxide in the ocean?
Did you draw arrows indicating how carbon moves within and between both living and nonliving parts of the environment?
Did you include short phrases on your poster to summarize what occurs at each stage of the carbon?
Did you write several paragraphs describing the full carbon cycle in detail? Did you discuss all
components of your poster in this paper?
Did you describe the exchange of carbon through carbon-containing compounds between the
organism and the environment?
Did you describe the contributions of photosynthesis and cellular respiration within and among
the four spheres? Did you discuss how carbon enters and leaves each of the four spheres
and in what forms?
Did you discuss the role of carbon storage in organisms?
Did you explain how a model of the carbon cycle is different from the actual cycling of carbon
in an ecosystem?
Did you double-check for correct sentence structure, punctuation, grammar, and spelling in your paper?

The model doesn't have to be on paper it can be a digital one.
Please do the model and the paragraphs.
THANK YOU!
