Competition is a relationship between organisms in which one is harmed when both are trying to use the same resource related to growth, reproduction, or survivability. Competition stems from the fact that resources are limited. There are simply not enough of some resources for all individuals to have equal access and supply. Competition can occur b...
Intraspecific Competition
Intraspecific competition is a density-dependent form of competition. “Intra” refers to within a species, as opposed to “inter” which means between. Intraspecific competition can be summed up in the image below. In this image, two wild dogs known as Dholes fight over a carcass. The carcass is a resource, something both organisms need to survive. Intraspecific competition is density dependent for one reason. The more dholes you have, the less food each one gets. To the individual dhole, food i...
Interspecific Competition
Interspecific competition is between individuals which are different species. This could be between any two species, as long as they are competing over a resource. An interesting example of interspecific competition is found in coastal marine environments, like the coral reef in the picture below. In this picture, there are dozens of species. There are several species of fish. Behind them, as a backdrop many people would ignore, is a canvas of dozens of species of coral. Coral, while it may l...
Direct and Indirect Competition
There is also another aspect of competition that can be applied to scenarios of limited resources, and that is the idea of direct vs indirect competition. Direct competition is like both of the scenarios above, and there are many more examples of it. Any time two or more animals fight or have a symbolized confrontation, this is probably some sort of competition for a resource. However, indirect competition is when the two animals do not interact, but the presence of both animals in the same t...
Competition is not a static process. Once set in motion, it can go a number of different ways. While the models may show that it will eventually drive one species to extinction, in reality a number of things can happen. First, an environmental disturbance, such as a fire or large wave, can upset the ecosystem and destroy the advantage the best comp...

What is the difference between intra- and interspecific competition? A. Intraspecific is between members of the same species B. Interspecific is between ...

One of the genes for coat colour in horses is Agouti. This gene for coat colour is found on the same position on the same chromosome for all horses. Hypothetically there are two different forms (alleles) of that gene found in horses: A and a. Each allele can produce a different coat colour: Allele A → black coat. Allele a → chestnut coat.

Competition (biology) Competition is an interaction between organisms or species in which both require a resource that is in limited supply (such as food, water, or territory). [1] Competition lowers the fitness of both organisms involved since the presence of one of the organisms always reduces the amount of the resource available to the other.
