Document Summary
Competition occurs when individuals living in the same group require the same resources, such as prey, water, light, and nutrients. In exploitation competition, every individual use the same resources, so that can make one species to die. In interference competition, every individual interferes with other individuals for the survival, and because they compete with each other for the resources they cannot live longer and will die at some point. (molumby, 151) According to the lab manual, competition is a sort of interspecific interaction, which shows how species interact with each other differently. There are five other types of interspecific interactions. Neutralism is the most common type of interspecific interaction, and species do not affect with each other. In commensalism, one species benefits and the other is unaffected. In amensalism, one species suffers while the other is not affected. Mutualism is the interaction in which when both species benefit from each other.
