Predation is when one organism eats another organism to obtain nutrients. The organism that is eaten is called the prey. Examples of predation are owls that eat mice, and lions that eat gazelles. Competition is when individuals or populations compete for the same resource, and can occur within or between species.redation is when one organism eats another organism to obtain nutrients.

In ecology, biological interactions can involve individuals of the same species (intraspecific interactions) or individuals of different species (interspecific interactions).These can be further classified by either the mechanism of the interaction or the strength, duration and direction of their effects.iological interactions are the effects that the organisms in a community have on one another. In the natural world no organism exists in absolute isolation, and thus every organism must interact with the environment and other organisms.
