Verified step by step guidance1
Understand the concept of dispersion patterns: Dispersion patterns describe how individuals in a population are spaced out across an area. The main types are clumped, uniform, and random.
Identify the characteristics of clumped dispersion: In clumped dispersion, individuals are grouped together in patches, often due to uneven distribution of resources such as food, water, or shelter.
Consider why resources might lead to clumped dispersion: When resources are unevenly distributed, organisms tend to gather where resources are abundant, leading to a clumped pattern.
Differentiate clumped dispersion from other patterns: Unlike uniform dispersion, where individuals are evenly spaced, or random dispersion, where spacing is unpredictable, clumped dispersion is characterized by groups of individuals in specific areas.
Apply this understanding to the problem: Given that the problem states resources are unevenly distributed, the most likely dispersion pattern is clumped, as organisms will gather in areas where resources are available.
