A student observing birds in a park records some ways that birds interact with living and nonliving parts of their environment. All the following observations are ways that a bird interacts with nonliving parts of its environment except —

Describe the differences between Complete and Incomplete Metamorphosis.
Answers will varry:

Complete metamorphosis has 4 stages and a BIG change occurs. The larva and pupa stage are the biggest differences between complete and incomplete metamorphosis. Larva is worm-like, Pupa is a cacoon or chrysalis. 

Incomplete nymph stage is a smaller version of the adult with no wings.

What is a decomposers role in a food chain or food web?

Decomposers break down dead plants and animals and return nutrients to the soil to help living plants grow.

Describe what would happen if all of the primary consumers in a food web died. 
The producers would increase, because their predator would be gone.

The secondary and tertiary consumers would decrease from lack of prey.

Explain the Carbon Dioxide-Oxygen Cycle.
Plants take in Carbon Dioxide for Photosynthesis and produce Oxygen, Animals and humans breathe in the Oxygen produced by plants and breathe out Carbon Dioxide that the plants will take in, and the cycle continues.
