Question

The rate of formation of new organic matter by consumers, and the biomass available for consumption of herbivores as well as decomposers are referred to as ______.

Options

• Gross primary productivity and Net primary productivity

• Net primary productivity and Secondary productivity

• Secondary productivity and Net primary productivity

• Secondary productivity and Gross primary productivity

Answer 1

The rate of formation of new organic matter by consumers, and the biomass available for consumption of herbivores as well as decomposers are referred to as Net primary productivity and Secondary productivity.

Explanation:

After deducting respiratory losses, the energy that remains in producers (plants) is known as net primary productivity, or NPP. It stands for the biomass that herbivores and decomposers can eat.
The rate at which consumers-herbivores and carnivores-create new organic matter by consuming and consuming food is known as secondary productivity. The biomass produced at higher trophic levels is reflected in it.
