Question

Discuss the gross primary productivity is more efficient than net primary productivity.

Answer 1

Gross primary productivity: 

1. It refers to the total amount of food energy or organic matter produced in an ecosystem by autotrophs.

2. GPP = NPP + Respiration

Net primary productivity:

1. It refers to the amount of energy that remain in autotrophs after respiration loss. 

2. NPP = GPP – Respiration
