Answer:
Net primary productivity = 24,500 kcal/m²
Explanation:
Given:
Gross primary productivity = 38,000 kcal/m²
Respiration amount = 13,500 kcal/m²
Find:
Net primary productivity
Computation:
Net primary productivity = Gross primary productivity - Respiration amount
Net primary productivity = 38,000 - 13,500
Net primary productivity = 24,500 kcal/m²
