The rate of formation of new organic matter by rabbit in a grassland is called
A
Gross primary productivity
B
Net productivity
C
Secondary productivity
D

Detailed Solution
Primary productivity is the rate at which producers (green plants) form biomass by photosynthesis; gross and net primary productivity both refer to producers.
Secondary productivity is defined as the rate of formation of new organic matter by consumers.
A rabbit is a herbivore, i.e., a primary consumer feeding on the grass.
Therefore the organic matter it forms from the food it eats is secondary productivity.
Hence the answer is secondary productivity.
