9. An interaction in which two organisms compete for survival.
a. Commensalism b: Competition c. Mutualism d. Parasitism e. Predation

Commensalism is a symbiosis in which one organism benefits from, and is often completely dependent on, the other for food, shelter, or locomotion, with no obvious effect on the host.

Mutualism describes the ecological interaction between two or more species where each species has a net benefit.

members of two different species use the same limited resource and therefore compete for it. Competition negatively affects both participants (-/- interaction), as either species would have higher survival and reproduction if the other was absent.
