Ecology The study of how living things interact with nature Biotic The living parts of the environment abiotic Non Living parts of the environment population All of the members of a species in an area community All of the different organisms in an ecosystem ecosystem A community of organisms and their environment. biosphere All of the living space on earth. herbivore An animal that eats only plants carnivore An animal that eats only other animals omnivore An animal that eats plants and animals food chain A diagram showing how energy passes from one organism to the next food web A diagram showing all of the connected food chains in an ecosystem energy pyramid A diagram showing how energy decreases as it goes up a food chain. carrying capacity The maximum number of organisms of a species an ecosystem can hold prey An organism that is hunted for food predator An organism that hunts others for food symbiosis A relationship where two different specieslive closely and interact often. mutualism A type of symbiosis is when two species help each other. commensalism A type of symbiosis when one species benefits from another but the second species isn’t affected Competition When two organisms fight over the same resources parasitism A type of relationship where one organism benefits while harming the other organism. coevolution When a relationship between two species causes them both to adapt. decomposition When dead organisms break down into simpler chemicals combustion When a material is burned decomposer An organism that breaks down material in dead organisms. succession When a destroyed ecosystem recovers pioneer species The first species to return to a destroyed ecosystem biome A large group of similar ecosystems with similar climate and similar organisms savanna A hot dry grassland with large herds and a few trees. Found in africa desert A hot and dry biome with very little water. tundra A very cold and very dry biome where parts of the ground are permanently frozen. plankton An organism that acts as a producer for marine ecosystems. estuary A area where freshwater and saltwater mix. wetland An ecosystem that is frequently flooded and has very wet soil. Biodiversity Large different organisms
