Question

Explain the terms GPP and NPP with examples.

Answer 1

GPP stands for gross primary productivity.
GPP is the rate at which ecosystem’s producers store and capture provided amount of energy as biomass in a given time duration. 
Example :used in respiration at cellular level, development and growth of the plant.


NPP stands for net primary productivity.
The loss of energy which is generated from the process of GPP, is termed as net primary productivity. 
Example :used in various sectors to calculate the yield of crop.

Answer 2

The terms GPP and NPP is explained below :

GPP

1. Full form of this term is Gross Primary Productivity.

2. It is the rate in which production of organic matter occurs during the process of photosynthesis.

3. Example : Plants uses small amount of GPP while they respire.

NPP

1. Net Primary Productivity is the full form of this term.

2. It is the term which indicates the biomass that is available for the heterotrophs' consumption.
