BRAINCAKEInterspecific Competition
Interspecific competition is competition between individuals of different species for the same limited resources, such as food, water, light, space, minerals or nesting sites.
When two species compete, the resources available to each are reduced. Each population therefore has less energy for growth and reproduction, so both populations are usually smaller than they would be if the other species were absent.
