Look back at your pictures of the models you made.
6. Analyze your models to determine whether you have included all the parts of the
chemical equations shown in Step 1. For example, you may not have modeled the
source of the energy used to make the products of photosynthesis or shown that
about 30 ATP molecules are made during cellular respiration. Think about any
elements you left out and how you could include them now to improve your model.
Then consider whether you have shown all the details involved in the flow of matter
and energy in the biosphere via these two reactions. Also consider whether
someone who does not know how you made the models would be able to
understand what each part of the overall model represents.
7. Next, you will combine your individual diagrams into a single model that
represents the overall flow of energy and matter in the biosphere. Make a plan for
improving any parts of your model so that they more clearly show the flow of matter
and energy in the biosphere. Make as many improvements as you can think of,
including at least one major improvement that makes your model clearer and more
meaningful. Draw a detailed diagram of your improved model in the space below. If
you have enough materials, build the improved model and take and attach a photo of
it. (10 points)
