Document Summary
The ways that species interact with others affect the resources use and population sizes of the species in an ecosystem. One benefits and the other is mutual. Most species compete with one another for certain resources. Compete to use the same limited resources. Species may only use parts of resource. Ex. night and day, fall and spring. As long as there is enough of the resource. Different types of birds share different parts of the same tree. Predator=feeds directly on all or part of a living organism. Parasite is usually much smaller than the host. If the host dies, they can"t feed off of it anymore and then the parasite dies. Both get what they want and form a tight interaction. Ex. hippos have fish all over them to clean the parasites and bacteria from their skin. Benefits one species and has little effect on the other. Group of interbreeding individuals of the same species.
