My Opinion

In my opinion this unit is relevant to my everyday life because there are many organisms all around us in our everyday life. Everywhere we look there are composers, producers, decomposers, and etc. in our very own environment and we also help play a very important role our self.

1. Compare and Contrast the decomposers in an environment to the producers.

2. Explain why an ecosystem would suffer if there was a shortage of producers.

3. How does a producer provide food for its ecosystem?

4. Why is it important for there to be different roles in an environment instead of every organism doing the same thing?

5. Explain the role of a decomposer in an ecosystem.

6. How does the process of photosynthesis affect an ecosystem?

7. What is the major source of energy for ecosystems?

8. Explain the difference between a food web and a food chain.

9. Why is it important for various species in an ecosystem to co-exist and cooperate?

10. How does a consumer obtain its food?
