What role do decomposers play in a food web?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and making them available for producers.

What happens to a food web if a primary consumer is removed?

Back

If a primary consumer is removed, the population of producers may increase due to less consumption, while secondary consumers may decrease due to lack of food.

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

How do energy and nutrients flow in a food web?

Back

Energy flows from producers to primary consumers, then to secondary consumers, and so on, while nutrients are recycled by decomposers.
