| Ecosystem | all the living and non living things in a given area-can be as tiny as a drop of water or as large as an ocean or forest. |

| Biotic factor | the living parts of an ecosystem. |
| Habitat | a place in which an organism lives- provides shelter, food, and other resources needed for survival. |
| Population | A group of organisms of the same species living together in the same area. |
| Species | A group of similar organisms that can produce fertile offspring. |

| Trophic cascade | The secondary effect that part down the food chain after the removal of a top predator from an ecosystem. |

| Food chain | Food energy transferred from one organism to another by eating. |
| Food web | All the possible overlapping food chains in an ecosystem. |
| Feeding level | Location producer is the primary consumer the third Tertiary. |
| Energy pyramid | Shows the amount of energy that moves from one feeding level to another more energy is available at the base of the pyramid then at the top |
| Competition | When organisms use the same limited resources they can be divided between two species or individuals within a species |
| Predation | When one animal eats another animal not a plant the predator eat the prey |
