400

I eat dead organisms but do not bring nutrients back to the earth. What am I?

What is a scavenger?

500

What is the complete role of decomposers? Be specific

500

500

What is an ecological niche?

the specific job an organism has. For example, wolve's niche is to keep deer population low.

500

Why is energy flow different in a food web compared to a food chain?

Food webs are more complete and cyclical. Food chains are one direction, linear.
