Which term describes how individuals in a population are distributed (clumped, random, uniform)?
Correct Answer:
Dispersion
Explanation:
Dispersion describes how individuals in a population are spread in space. It captures the spatial patterns—whether organisms occur in clumps, appear in a random arrangement, or maintain even spacing. This concept helps explain how resource distribution, social behavior, and environmental conditions shape where individuals are found. By contrast, age structure looks at how many individuals are in each age class, habitat refers to the physical environment where organisms live, and niche describes the role and resource use of a species in its ecosystem. So dispersion is the term that describes the distribution pattern of individuals.
