What is Gross Primary Productivity (GPP)?
Total energy captured by producers through photosynthesis.
Define Respiration in plants.
Process where plants use captured energy for their needs, releasing some as heat.
What is Net Primary Productivity (NPP)?
Energy remaining after plants use some for respiration; energy available to other organisms.
What is the relationship between GPP and NPP?
NPP = GPP - Respiration. NPP is the energy available after respiration.
Why is NPP important for an ecosystem?
Determines how much life an ecosystem can support; higher NPP means more biodiversity.
How does energy flow in an ecosystem?
Energy flows from the sun to producers (GPP), then some is lost to respiration, and the remainder (NPP) is available to other organisms.
