Class 12 NEET Biology Organisms and Populations

(a) : Competition is rivalry for obtaining the same resource. Competition is of two types, intra specific and interspecific. Intra specific competition is the competition amongst members of the same species for a common resource. It may be for food, space, and mate. So if the density of elephant population in an area increases, it will lead to intra specific competition. This will lead to the establishment of territories in elephants which will result in pushing out of the extra number securing shelter, mate and food for the rest.
