What is the relationship between Net Primary Productivity (NPP) and Gross Primary Productivity (GPP)?

  1. NPP = GPP + Respiration (R)
  2. NPP = GPP - Respiration (R)
  3. GPP = NPP - Respiration (R)
  4. NPP = GPP / Respiration (R)
Show answer and explanation

Correct answer: NPP = GPP - Respiration (R)

Net Primary Productivity is the weight of organic matter stored by producers after accounting for respiratory losses. It represents the actual biomass available for consumption by heterotrophs.
