Detailed explanation-1: -Competition is most typically considered the interaction of individuals that vie for a common resource that is in limited supply, but more generally can be defined as the direct or indirect interaction of organisms that leads to a change in fitness when the organisms share the same resource.

Detailed explanation-2: -Organisms from different species compete for resources as well, called interspecies competition. For example, sharks, dolphins, and seabirds often eat the same type of fish in ocean ecosystems.

Detailed explanation-3: -Competition will occur between organisms in an ecosystem when their niches overlap, they both try to use the same resource and the resource is in short supply. Animals compete for food, water and space to live. Plants compete for light, water, minerals and root space.
