What is Net Primary Productivity?
Net Primary Productivity (NPP) refers to the rate at which plants and other autotrophic organisms convert solar energy into chemical energy through photosynthesis, minus the energy expended during cellular respiration. In simpler terms, it represents the amount of organic matter (biomass) that is produced by green plants in an ecosystem after accounting for the energy they use for their own metabolic processes. NPP is a key measure of ecosystem productivity and plays an important role in supporting food webs, carbon cycling, and overall ecosystem functioning.

Net Primary Productivity
Net Primary Productivity (NPP) is an important measure of the health of an ecosystem. It is used to calculate the amount of food available to consumers, and it can also be used to track changes in the ecosystem over time. NPP is calculated by measuring the increase in biomass in a unit area over a period of time.
It is typically expressed in units of grams of carbon per square meter per year. In this article, we will cover Net Primary Productivity (NPP) in detail.
