Question

The biomass available for consumption by the herbivores and the decomposers is called

• A. Net primary productivity
• B. Secondary productivity
• C. Standing crop
• D. Gross primary productivity

Answer 1

The correct option is A Net primary productivity

Carbon that is stored in terrestrial plants mainly through photosynthesis is called net primary production or NPP and is the dominant source of food, fuel, fiber, and feed for herbivores and decomposers. So A is the correct option.
A standing crop is the total biomass of an ecosystem or any of its components at a given time.
The rate at which these consumers convert the chemical energy of their food into their own biomass is called secondary productivity.
Gross Primary Productivity is the total rate at which the ecosystem capture and store carbon as plant biomass, for a given length of time.
