Occurs when members of two or more species interact to gain access to the same limited resources such as food, light, or space.
Occurs when a member of one species (the predator) feeds directly on all or part of a member of another species (the prey)
Occurs when one organism (the parasite) feeds on the body of, or the energy used by, another organism (the host), usually by living on or in the host

In predation, a member of one species (the predator) feeds directly on all or part of a living organism of another plant or animal species (the prey) as part of a food web. Together, the two different species form
Predator prey relationship
When populations of two different species interact in this way over a such long period of time, change in the gene pool of one species can lead to changes in the gene pool of other species. Such changes can help both sides to become more competitive or can help to avoid or reduce competition
