Question 1 Report

Which of the following is not an effect of overcrowding on a population?
Answer Details
The answer to the question is (c) Commensalism. Commensalism is a type of symbiotic relationship between two organisms where one organism benefits without affecting the other. Overcrowding can lead to several negative effects on a population such as increased competition for resources, aggression among individuals, and even cannibalism in some cases. Death can also occur due to the spread of diseases in overcrowded populations. However, commensalism is not a negative effect of overcrowding. It is a relationship that occurs between two organisms in a neutral or positive way, without any harm or benefit to the other.
