What is the difference between interspecific and intraspecific interactions

What is the difference between interspecific competition and intraspecific competition? Define competition: competition is an interaction between organisms where one organism has a negative effect on the fitness of the other organism Define interspecific competition : competition between organisms of different species Define intraspecific competition : competition between organisms of the same species Key tip: the question asks you to compare - use terms such as whereas and in contrast.

Answered by Zoe G. Competition Competition is a relationship between organisms that strive for the same resources in the same place. There are two different types of competition: Intraspecific competition occurs between members of the same species.

For example, two male birds of the same species might compete for mates in the same area. This type of competition is a basic factor in natural selection. It leads to the evolution of better adaptations within a species.

Interspecific competition occurs between members of different species. For example, predators of different species might compete for the same prey. They are:. Figure 1: Competition Between Panthera leo and Crocuta crocuta. There are two other types of interspecific competition based on the outcome. Intraspecific competition is the competition among members of the same species for limited resources in the same ecological area.

It depends on the density of the population and the influence of this type of competition is high in a highly-dense population. More importantly, it is one of the main driving forces for evolution since it changes the population dynamics such as population size and composition.

Here, only the individuals that are most suitable to the environment can survive. Male peacocks and elk both exhibit striking features, which they evolved as a result of sexual selection.
