In intraspecific competition, groups or individuals of the same species go after the same resources, since they all need the same things to survive. Intraspecific is just competition between individuals of the same species. Interspecific competition, in ecology, is a form of competition in which individuals of different species compete for the same resources in an ecosystem (e.g. Competition is a relationship between organisms that strive for the same resources in the same place. This is an example of interspecific competition because the branching coral and the ascidian are both competing for resources. 28 Feb. 2015. This leads to a reduction in fitness for both individuals, but the more fit individual survives and is able to reproduce. interspecific competition, very little is known about intra-specific competition in reef building corals.

We conclude that intraspecific competition in reef corals involves great investment of energy. Interspecific competition can be studied using mathematical models that have been specifically developed for the purpose by ecologists. The ecological significance and the different pathways of this competition are discussed. Sponges are very abundant in coral reefs. In this image, two wild dogs known as Dholes fight over a carcass. Intraspecific competition may not affect populations that are well below their carrying capacity, as resources are plentiful and all individuals can obtain what they need.
