| Question | Answer |
|---|---|
| Ecology | Study of interactions between organisms and enviroment |
| Autotrophs | Organisms that use sunlight or energy to make food |
| Producers | organisms that make their own food |
| Photosyntheisis | Process used my autotrophs to make food from the energy from the sun |
| Chemosynthesis | Autotrophs that capurtue the cemical energy since they live in places without sunlights |
| decomposer | break down waste and organis matter and return to the ecostytem |
| hebivore | eats only plants |
| carnivore | eats only animals |
| omnivore | eats both plants and animals |
| comsumers | cants make their own food |
| food chains | show how much matter and energy move through the ecosystem in a series of steps, showing which organisms transfer energy by eaten or being eaten |
| food web | models that show all psooible feeding relationship at each trophic level in a community; links all food chains in an ecosystem |
| biogeochemical cycles | elements, compounds, and other forms of matter are passed from one organismto another and from one part of the biosphere to another; connect biological,geological and chemical aspects |
| water cycle | shows that water is constantly moving between the atmosphere and earth |
| biotic factors | all living or once living organisms in an enviroment |
| aboitic factors | all nonliving parts of the envirment |
| habitat | an area where and organism lives including both biotic and abiotic factors |
| niche | all stategies and adaptations a species live closely |
| niche | all strategies and adaptations a specie uses in it environment |
| symbiosis | any relationship in which two species live closely together |
| predators | organisms that seek out and eat other organisms |
| prey | organisms that are being eaten |
| mutualism | both species benefit from relationship |
| commensalim | one organism benefits and the other is neither helped nor harmed |
| parasitism | one organism lives on or in organisms that harms it |
| limiting factor | anything that limits an organisms ability to live in a particular enviroment |
| tolerance | the ability of living things to survive the changes in their enviroment |
| succession | the process of gradual natural change in species |
| Biome | large group of ecosystems that share the same type of climax community |
| aquatic biome | biomes located in bodies of water |
| terrestial biome | biomes located on land |
| tundra | coldest biome, permanently frozen |
| taiga | pine trees, long and cold winters |
| desert | hot and dry, rocky soil |
| savannah | warm and limited rain open grasslands |
| temperate forest | warm summers and cold winters, fertile soil, leafy trees |
| tropical rain forest | hot, plentiful rain, abundance of plant and animal species |
