Question

Quizplus · Accepted Answer

Net primary productivity is the amount of organic matter that is produced in an ecosystem through photosynthesis after accounting for the energy used by plants through respiration. The greatest net primary productivity is found in the tropics because of the high temperatures and abundant rainfall, which provide optimal conditions for plant growth. Additionally, the abundance of light due to the position of the tropics near the equator further stimulates photosynthesis.
