Competition is an interaction between populations in which they compete for limited resources. Here we have two populations - a population of lions and a population of hyenas.<span> If resources (water, sunlight, territory, food, in this example, an animal carcass) are limited and several populations depend on these resources, then, they must compete to gain the resources. </span>
A population is a group of organisms of the same species living in a particular place. A family of lions and a family of hyenas are two distinct populations. Together, the populations of the hyenas and the lions make up a community.
