Question

What is net primary productivity of an ecosystem?

Answer 1

Net Primary Productivity (NPP) is the amount of carbon uptake after subtracting Plant Respiration (RES) from Gross Primary Productivity(GPP). GPP is the total rate at which the ecosystem capture and store carbon as plant biomass, for a given length of time.


Hope it's helps you.

Answer 2

Explanation:

According to NCERT,

Plants take <50 % of sunlight

It uses 2-10 % of it for photosynthesis  (GPP)

ie  1-5 % of total radiation (PAR)

For respiration, it uses 20 %

ie  0.2 - 1 % of GPP

Amount left is NPP

ie 0.8 -4 % of GPP

or 1.6 - 8% of PAR
