Secondary productivity is the rate of formation of new organic matter by
Correct answer: A. consumers
- A. consumers
- B. decomposers
- C. producers
- D. parasites.
Explanation
The rate of photosynthesis of organic matter by the consumers is known as secondary productivity. It depends upon the loss while transferring energy-containing organic matter from the previous trophic level plus the consumption due to respiration and predation. Therefore, net productivity decreases with each trophic level.
