Ecosystem ✔✔A community and its abiotic... conditions. Population ✔✔A group of organisms of the same species living in a certain area at a certain time. Habitat ✔✔The environment in which a species normally lives or the location of a living organism. Species ✔✔A number of organisms which can interbreed to produce fertile offspring. Niche ✔✔The role an organism plays in its community. Trophic level ✔✔The place of an organism in a food chain or web. Autotroph ✔✔An organism which makes its own food using inorganic sources of carbon. Heterotroph ✔✔An organism which requires pre-formed organic molecules, which ingests organic material. Producer ✔✔The first trophic level in a food chain which provides the energy for subsequent levels. Consumer ✔✔An organism which gets its nutrients and energy by ingesting other organisms or parts of them. Community ✔✔A group of interacting populations in a certain area. Detritivore ✔✔An animal that consumes decomposing organic particles getting its nutrients primarily from microbes on these particles. Saprotroph ✔✔Organism that feeds by secreting digestive enzymes onto its food source and absorbing the products of digestion. Carrying capacity ✔✔Maximum average/biomass of organisms that can be sustained by an area in the long term. Random sample ✔✔A sampling method used to ensure that every individual in a studied area has an equal chance of being observed. Evolution ✔✔The process of cumulative change of heritable characteristics of a population. Herbivory ✔✔A form of interaction where a primary consumer feeds upon a producer. Predation ✔✔A form of interaction where a consumer feeds upon another consumer. Parasitism ✔✔A form of interaction where an organism lives in or in a host and obtains food from it. The host is always harmed. Competition ✔✔A form of interaction where two species compete if the amount one species uses reduces the amount available to the other. Mutualism ✔✔A form of interaction where members of different species live in a close relationship from which both benefit. Fundamental niche ✔✔The full potential range of the physical, chemical, and biological factors a species can use if there is no competition from other species. Realized niche ✔✔The part of its fundamental niche that a species actually occupies. [Show More]
