A carnivore that eats other carnivores. Tertiary consumers
Dead organic matter. Detritus
The amount of light energy converted to chemical energy (organic compounds) by the autotrophs in an ecosystem during a given time period. Primary production
The total primary production of an ecosystem. Gross primary production (GPP)
The gross primary production of an ecosystem minus the energy used by the producers for respiration. Net primary production (NPP)
An element that must be added for production to increase in a particular area. Limiting nutrient
The amount of chemical energy in consumers' food that is converted to their own new biomass during a given time period. Secondary production
The percentage of energy stored in assimilated food that is not used for respiration or eliminated as waste Production efficiency
The percentage of production transferred from one trophic level to the next. Trophic efficiency
The amount of added nutrient, usually nitrogen or phosphorus, that can be absorbed by plants without damaging ecosystem integrity. Critical load
A process by which nutrients, particularly phosphorus and nitrogen, become highly concentrated in a body of water, leading to increased growth of organisms such as algae or cyanobacteria. Eutrophication
The warming of Earth due to the atmospheric accumulation of carbon dioxide and certain other gases, which absorb reflected infrared radiation and reradiate some of it back toward Earth. Greenhouse effect
