Intraspecific competition involves an interaction where by members of the same species compete for limited supply of resources. The end result is the reduction in fitness for both individuals. Animals can reduce the intensity of intraspecific competition by exploiting different type of food resources and also moving to other areas that are sparsely populated and with high amounts of food.
Explanation:
Natural selection is the mechanism that is responsible for the evolution of organisms.
In the given case, the Freshwater shrimp has been introduced to a pond in which the two species with variations are introduced.
The <em>C. cantonensis </em>is brighter in color whereas the <em>C. multidentata</em> is mottled drab in color. The predator fish can feed easily on the species which is brighter therefore <em>C. cantonensis</em> is more susceptible. The mottled drab species is not easily predated by the species.
The 30 % offsprings of <em>C. cantonensis</em> can survive till the reproductive age whereas 75% of C. multidentata. This shows that natural selection has acted on the color of the shrimp species selected against the predator fish species.
The species with mottled drab color is the result of the differential reproductive rate.
