Detailed explanation-1: -a clumped population distribution always has more individuals than a uniform distribution. Population growth rate is how fast a population changes in size over time. A population’s age-sex structure influences population growth, as older people are more likely to reproduce.

Detailed explanation-2: -Individuals may be distributed in a uniform, random, or clumped pattern. Uniform means that the population is evenly spaced, random indicates random spacing, and clumped means that the population is distributed in clusters.

Detailed explanation-3: -Clumped dispersion is seen in plants that drop their seeds straight to the ground, such as oak trees, or animals that live in groups, such as schools of fish or herds of elephants.

Detailed explanation-4: -An advantage of a herd, community, or other clumped distribution allows a population to detect predators earlier, at a greater distance, and potentially mount an effective defense.

Detailed explanation-5: -Most populations live in clumps. Why clumps? 1. The resources a species needs vary greatly in availability form place to place, so the species tends to cluster where the resources are available.
