Biology Question on Eco-System
The biomass available for consumption by the herbivores and the decomposers is called
A
Secondary productivity
B
Standing crop
C
Gross primary productivity
D
Net primary productivity
Answer
Net primary productivity
Explanation
Solution
The total organic matter synthesised by the producers in the process of photosynthesis per unit time and area is known as gross primary productivity. Net primary productivity is equal to the rate of organic matter created by photosynthesis minus the rate of respiration and other losses. It is actually the biomass available for consumption by the herbivores and the decomposers.
