NEET Botany Ecosystem Components MCQ Question
Which of the following statements about ecosystem components is correct?
Gross primary productivity is the total amount of organic matter produced during photosynthesis.
Net primary productivity includes all organic matter produced without accounting for respiration.
Decomposers are not considered biotic components of an ecosystem.
Primary productivity is solely dependent on the abiotic components of an ecosystem.
Correct Answer
Detailed Explanation
Gross primary productivity (GPP) is indeed defined as the rate of production of organic matter during photosynthesis. In contrast, net primary productivity (NPP) accounts for respiration losses and is not solely about the total production. Decomposers are crucial biotic components, and primary productivity is influenced by both biotic and abiotic factors.
