Question

Give brief description of factors that affects primary productivity.

Expert Solution

Step 1

The total amount of energy that is trapped, or “fixed,” by all autotrophs in an ecosystem is called gross primary productivity. Autotrophs use most of this energy in respiration, producing ATP for their own growth, and reproduction. As they do so, they release heat energy. Heat energy is exchanged with the environment and leaves the food web. The remaining energy in the producer level is called net primary productivity. It is the amount of energy available for consumers to eat.
