Overview
Primary productivity is a fundamental concept in ecology that measures how much organic material is produced by photosynthetic organisms. It is divided into gross primary productivity (GPP), which is the total production, and net primary productivity (NPP), which accounts for the energy used by plan...
Key Terms
Example: GPP is measured in grams of carbon per square meter per year.
Example: NPP = GPP - Respiration.
Example: Plants use photosynthesis to produce glucose from carbon dioxide and water.
Example: A forest ecosystem includes trees, animals, and soil.
Example: Plants respire at night, using stored energy.
Example: Chlorophyll gives leaves their green color.
