| Term | Definition |
|---|---|
| Organism | Living things |
| Habitat | An environment that provides the things a specific organism needs to live grow and reproduce. |
| Biotic factor | Parts of a habitat that or were once alive and that interact with and organism |
| Abiotic factor | Nonliving parts of an organisms habitat. |
| Population | All members of one specie living in an particular area |
| Community | All the different populations that live together in an area |
| Ecology | The community of organisms that lives in a particular area, along with their environment |
| Ecosystem | The community of organisms that lives in a particular area along with a nonliving environment. |
| Species | a group of organisms that can mate with each other and produce offspring |
| Population density | The number of individuals in an area of a specific size. Population density can be represented as a equation. |
| Limiting factor | An environmental factor that causes a population to stop growing or to decrease in size. |
| Carrying capacity | The largest population that an area can support. |
| Producer | An organism that can make its own food |
| Consumer | Obtains energy by feeding on other organisms. |
| Decomposer | Break down biotic wastes and dead organisms, returning the law materials to the ecosystem |
| Food chain | A series of events in which one organism eats another and obtains energy and nutrients |
| Food web | Consists of many overlapping food chains in an ecosystem |
| Energy pyramid | Shows the amount of energy that moves from one feeding level to another in a food web |
| Photosynthesis | Set |

| Photosynthesis | Set of chemical reactions plants use to turn light, water, and nutrients into oxygen and energy, in the form of sugars. |
| Chlorophyll | Absorbs light, much like cells in solar panels do |
| Autotroph | An organism that makes its own food |

| Niche | The role of an organism in its habitat |
| Prediction | An interaction in which one organism kills another for food or nutrients |
| Competition | When two species share a niche, one of there populations might be affected |
| Symbiosis | Any relationship in which two species live closely together |
| Commensalism | Relationship in which one species benefits and the other species is neither helped nor harmed |
| Mutualism | Is a relationship in which both species benefit |
| Parasitism | A relationship that involves one organism living with, on, or inside another organism and harming it |
