Sun
What are consumers?
Consumers are living organisms that must eat to survive.

What do you call the relationship of two different types of organisms who live together?
A symbiotic relationship
When a new species that is not native to an area takes over the area so much that it affects the local ecosystem it is called an _____.

How is a food chain different from a food web?

Commensalism
Name something that could cause an animal to become endangered.

What is the definition of Photosynthesis?

Name at least one type of decomposer.
Possible Answers: Bacteria, Fungi, Mold, Mildew, Mushrooms, Earthworms, Pill Bugs, Flies, etc.
