Net primary productivity is used because organisms need to use some energy for their own:
AReproduction in spring
BDefence against predators
CRespiration and heat loss
DMovement across land
Answer & Solution
Correct answer: C. Respiration and heat loss
1. Not all captured energy stays available to the next level.
2. Gross primary productivity is the rate at which producers incorporate solar energy.
3. All organisms need to use some of this energy for their own functions.
4. Those functions are respiration and the resulting metabolic heat loss.
