Similar species can coexist in a community by using __________.

• A. resource partitioning
• B. mutualism
• C. competitive exclusion
• D. predation

Answer: (A)

Verified step by step guidance

1. Understand the concept of 'resource partitioning': This occurs when similar species coexist in the same community by dividing resources in a way that minimizes competition. For example, species may use different parts of a habitat or consume different types of food.
2. Review the concept of 'mutualism': Mutualism is a type of symbiotic relationship where both species benefit from the interaction. While mutualism can contribute to coexistence, it is not directly related to minimizing competition for resources.
3. Examine 'competitive exclusion': This principle states that two species competing for the exact same resources cannot coexist indefinitely. One species will outcompete the other, leading to the exclusion of the less competitive species.
4. Analyze 'predation': Predation involves one species (the predator) feeding on another species (the prey). While predation can influence population dynamics, it does not directly explain how similar species coexist by minimizing competition.
5. Conclude that 'resource partitioning' is the correct answer: It specifically addresses how similar species can coexist by dividing resources to reduce direct competition, allowing them to occupy different ecological niches.
