Unpacking Unit 7

Part 4 by Tanaya Battle


There are many factors that impact and makes up an ecosystem. All of these factors interact and coexist together to make life better and more productive. The lost or change  of one factor can also impact just as much as the others

Key Terms

Micro-organism: a microscopic organism especially a bacterium, virus, or fungus

Producers: a person or thing that makes or causes something

Consumer: a person or thing that eats or uses something

Decomposer: an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material

Bacteria: a member of a large group of unicellular microorganisms that have cell walls but lack organelles and an organized nucleus, that include some that can cause diseases

Fungi: any of a group of unicellular, multicellular, or syncytial spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools

Food webs: a system of interlocking and interdependent food chains

Photosynthesis: the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water

Co-exist: exist at the same time or in the same place

Ecosystem: a biological community of interacting organisms and their physical environment


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?
