Overcrowding in a population does not result in

Overcrowding in a population does not result in commensalism. Commensalism is a type of symbiotic relationship between two species where one species benefits while the other is neither harmed nor benefited. Overcrowding, on the other hand, can lead to competition for resources, such as food, water, and shelter, among individuals of the same species. It can also increase the transmission of diseases and parasites, resulting in death or migration of some individuals from the population. Therefore, overcrowding can have significant impacts on population dynamics, but it does not lead to commensalism.
