Competition takes place when two or more individuals compete for the same limited resources, such as food, water, space, shelter and mating partners.
Intraspecific competition takes place between individuals of the same species
The individuals of a particular species live in the same habitat and use the same resources; consequently intraspecific competition is a very intense type of competition.
Interspecific competition takes place between individuals of different species
Interspecific competition usually takes place between individuals with similar habitats and ecological niches
As the numbers of a population increase and resources become increasingly limited, intraspecific competition between individuals increases
With the increase of population numbers, the ecological niches of the different species may also overlap more and more, which will in turn increase interspecific competition.
