Study Notes
Primary Productivity
- The overall amount of biomass produced by primary producers in an ecosystem is referred to as primary productivity.
- Primary producers, such as plants and phytoplankton, convert CO2 into organic compounds through photosynthesis.
Trophic Levels
- Carnivores that feed on carnivores occupy the apex predator trophic level.
Photosynthesis
- The primary process responsible for the production of organic compounds from CO2 through photosynthesis is light-dependent reactions.
Terrestrial Primary Productivity
- The most highly correlated variables with terrestrial primary productivity are temperature, precipitation, and solar radiation.
Marine Primary Productivity
- The highest rates of primary production by marine phytoplankton are generally concentrated in upwelling regions, coastal areas, and near river mouths, where nutrient availability is high.
