What is the relationship between CO2 concentration and the rate of photosynthesis?

Back

As CO2 concentration increases, the rate of photosynthesis increases until it balances out.

Front

What is the role of producers in an ecosystem?

Back

Producers provide energy for consumers, and their health directly affects consumer populations.

Front

What evidence supports the claim that healthy producers lead to increased consumer populations?
