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 remains in autotrophs after respiration loss.
2. NPP = GPP – Respiration
