| Biotic Factor | a living factor in the environment; plants, animals, bacteria ect. |
| Abiotic Factor | a non-living factor in the environment; weather, soil, minerals, amount of water, sunlight ect. |
| Habitat | the place where an organism lives |
| Niche | the role the organism plays in the environment; what it is supposed to do, where it is supposed to live, what it is supposed to eat ect. |
| Resource | anything needed for survival |
| Parasitism | the type of symbiosis where one organism is helped and the other is harmed. The organism with the parasite is called the host. Example would be a tick on a dog. |
| Predation | the community interaction in which one animal hunts and eats other animals; predator/prey |
| Symbiosis | any relationship in a community where both species are living closely together |
| Mutualism | the type of symbiosis where both organisms benefit; example is a honey bee and a flower. The bee gets nectar and the flower gets pollinated. |
| Commensalism | the type of symbiosis where one organism benefits and the other is not affected; example is the bird on the bulls back. The bull walks through the grass and stirs up insects which in turn feed the bird. The bull is not affected either way. |
| Competitive Exclusion | when two organisms occupy the same niche, they will compete for resources. The organism that loses that competition usually fails to survive. |
