Discuss the differences between intraspecific and interspecific competition
What will be an ideal response?
Intraspecific competition is the competition for limited resources by members of the same species. This is part of the process of natural selection and determines which individuals are most fit and will survive to produce offspring under a given set of environmental conditions. Ultimately, this process benefits the species long term, since unfit genetic combinations are weeded out of the population. Interspecific competition occurs between different species. This is the only ecological interaction considered to be (-/-), since all species involved have smaller populations and fewer resources than if they were not competing. The long-term result will be for the competing species to evolve different strategies for survival and different resource use patterns, provided that one or more competitors is/are not extirpated by the stronger species.
