| Ammonification | process in which microorganisms convert plant and animal waste or dead organisms into ammonia |
| Biomass | The weight of an organism after the water has been removed |
| Circadium rythm | Daily,24-hour cycle of behavior in responce to inturnal biological cues. |
| Community | Several interacting populations that inhabit a common enviroment and are able to function because each organism within the ecosystem depends on other organisms. |
| Decomposer | Organisms,such as many bacteria and fungi in all ecosystems by breaking down and absorbing nutrients from dead and decaying organic matter. |
| Denitrification | process in which ammonia, nitrite, and nitrate become nitrogen gas |
| Ecological pyramid | Model used to show the movement of energy, biomass,and numbers, through a food chain |
| Ecology | Scientific study of interactions between organisms and their enviroments. |
| Ecosystem | Populations in a community and abiotic factors with which they interact. |
| Nitrification | two-step process by which ammonia becomes nitrate |
| Nitrogen fixation | process by which atmosphere nitrogen is incorporated into nitrogen compounds in the soil |
| Biome | An area of the earth that has the same climate and dominated by the same types of plants |
| Population | The number of organisms of the same species in a specific area |
| Symbiosis | A relationship of 2 organisms |
| Trophic level | feeding level within an ecosystem |
| Abiotic facter | Nonliving factors in an ecosystem like soil, water, air |
| Biotic facter | Living parts of an ecosystem like plants and animals |
| Habitat | The surrounding in which an organisms lives |
| Niche | The role in which an organism plays in its environment |
| Endangered species | a species of organisms that has a large decine in population |
| Producer | An organism that produce its own food like plants |
| Primary consumer | An organism that only eats producers |
| Secondary consumer | An organism that eats primary consumers |
| Teritory consumer | The top secondary consumers in an ecosystem |
| Herbivore | An organism that only eats plants |
| Carnivore | An organism that only eats meat |
| Omnivor | An organism that will eat both plants and animals |
| Predators | Hunters |
| Prey | Organism that are eaten by predators |
| Mutualism | Symbiotic relationship where both organisms benifit from each other |
| Commensalism | Symbiotic relationship in which 1 organism benifits and the other is not effected |
| Parasitism | Symbiotic relationship where 1 organism benefits and the other is harmed |
| Diurnal | Condition where an organism is active during the day time |
| Nocturnal | condition where an organism is active during night hours |
| Hibernation | A period of low activity in an organism during cold weather |
| Estivation | A period of low activity in an organism during hot weather |
