Ecology
| Term | Definition |
|---|---|
| Ecology | -The study of interactions that take place among organisms and their environment. |
| Organism | One individual that belongs to a certain species. |
| Population | All the organisms that belong to the same species living in a community. |
| Community | All the populations of different species that live in an ecosystem. |
| Predator | Consumers that capture and eat other consumers. |
| Prey | The organism that is captured by the predator |
| Biotic | features of the environment that are alive or were once alive. The prefix bio means life. |
| Ecosystem | All the living organisms that live in an area and the nonliving features of their Environment |
| Limiting Factors | -Anything that restricts the size of the population, including living and nonliving features of an ecosystem, such as predators or drought. |
| Abiotic | the non-living physical features of the environment, including air, water,sunlight, soil (rocks), temperature, and climate. The prefix A means not (living). |
| producer | an organism that converts simple inorganic matter (such as water and carbon dioxide) into organic matter (such as sugar and protein). |
| herbivore | an animal that primary eats plants, berries, fruits, leaves and other plant based foods. |
| omnivore | an animal that eats a variety of plants, animals, fungi, and algae |
| carnivoer | an animal that eats the flesh of other animals, or meat |
| scavenger | an animal that eats the remains of dead plants and animals or decaying biomass |
| decomposer | an organism that feeds off of dead things such as leaf litter and wood, animal carcasses, and fecal matter |
| sun | a star at the center of our solar system. It is a nearly perfect sphere of hot plasma that radiates visible light energy, infrared radiation with 10% ultralight radiation. |
| Ecological Succession | Ecological Succession is where a ecosystem changes over time. Sometimes this can be for hundreds of years. The species become more diverse and mature, over time. |
| Primary succession | A type of ecological succession in which no soil is present. Causes: glacier retreating, lava from a volcano erupting, and sand dunes |
| Secondary succession | A type of ecological succession in which soil is present. Examples: Disturbances such as human activities, flooding, fire (SSS) |
| Biome | Large geographical area that has similar climates and ecosystems |
| Pioneer species | the first organisms to move into an ecosystem (e.g. lichens/mosses) |
