| Term | Definition |
|---|---|
| Ecology | Study how organisms interact with eachother as well as with their enviroment in a system. |
| Enviroment | All living things and nonliving things that exist on earth. |
| Habitat | The natural home or environment of an animal, plant, or other organism. |
| Abiotic | Non living things, physical things such as , minerals, air or things measured such as temperature, hours of daylight, salt .concentration |
| QQBiotic | Living, these factors are organism such as plants, animals, mushrooms, bacteria, algae. |
| Ecosystem | A complex self regulating system in which living things interact with living and non living things. |
| Natural Ecosystem | A natural ecosystem is neither planned nor maintained by people. |
| Artificial Ecosystem | Artificial Ecosystem is planned and maintained by people. Examples: City, Zoo, Aquarium, Farm |
| Herbivores | An animal that eats ONLY plants. |
| Carnivores | An animal that eats mostly meat. |
| Omnivores | An animal that eats both plants and meat. |
| Predators | Animals that catches and feeds off of other live animals. |
| Scavengers | An animal that mostly eats decaying biomass. |
| Parasites | Obtain their food by feeding off another organism which continues to live. |
| Detritivores | A consumer that feeds on organic matter. |
| Population | A group of member of same species that live in the same area. |
| Community | Populations of different species that live and interact in the same area. |
| Ecosystem | Interaction of community and surrounding abiotic components. |
| Biome | Large geographical region that contains similar ecosystems. |
| Biosphere | A part of our planet, including water, land and air, where life exists. Biomes combine to form this... >> organized<< |
| Biodiversity | Number and range of different organisms in an area. |
| Toxins | Harmful substances that contaminate the air, water, soil, and food, potentially causing health problems for organisms. Bioaccumu. |
| Bioaccumulation | Gradual build-up of chemicals in an organism’s body \. |
| Photosynthesis | The process plants use to produce carbohydrates from carbon dioxide, water, and sunlight. |
| Respiration | The operation in which organisms within a specified ecosystem use the process to convert organic carbon to carbon dioxide. |
| Extirpated | Species that no longer exist in a particular region but still occurs elsewhere. |
| Amphibious | Born in water, breathing with gills but can live on land or in water. |
| Autotroph | Organisms that can make their own food from basic nutrients and sunlight. Examples:green plant, algae. |
| Heterotroph | Organisms that must feed on other organisms to obtain energy. |
| Carrying capacity | Maximum number of individuals that an ecosystem can support without reducing its ability to support future generations of the same species. |
| Commensalism | Type of symbiosis in which one species benefits from a relationship without helping or harming the other species. |
| Mutualism | A type of symbiosis in which both species benefit from the symbiotic partnership. |
| Symbiosis | Close interaction between two different species in which members of one species lives in on or near members of another species. |
| Terrestrial | Land-based animal. |
| Food Webs | A pictorial representation of the feeding relationships among organisms in an ecosystem. |
| Food chains | Show two important things: A step-by-step sequence of who eats whom in an ecosystem. The one-way flow of energy from the producer to the top level consumer. |
