Question

Define productivity in an ecosystem.

Hint:

Remember: Productivity measures energy production in an ecosystem; GPP includes total energy, and NPP is available for consumers. 

Answer 1

Productivity in an ecosystem refers to the rate at which biomass or organic matter is produced by producers through photosynthesis. Ecosystem productivity is categorized into gross primary productivity (GPP), which is the total rate of photosynthesis, and net primary productivity (NPP), which is the energy remaining after respiratory losses.
