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.
Why is NPP important for an ecosystem?
It determines how much life an ecosystem can support, influencing biodiversity and trophic levels.
How does energy flow in an ecosystem?
Energy enters as sunlight, is captured by producers (GPP), some is lost through respiration, and the remainder (NPP) supports the ecosystem.
What is the relationship between GPP and NPP?
NPP = GPP - Respiration. NPP is the energy available to the ecosystem after producers meet their own needs.
What are the basic steps in calculating NPP?
- Measure GPP (total energy captured). 2. Measure respiration (energy used by producers). 3. Subtract respiration from GPP: NPP = GPP - Respiration.
