Populations are groups of individuals of the same species. This type of distribution is the most common and can occur when resources are patchy or regionally concentrated. Clumping is a behavior in an organism, usually sessile, in which individuals of a particular species group close to one another for beneficial purposes. It is important to note that most of the physical factors influence population distribution only indirectly through climatic conditions.

For example, the sage plant, Salvia leucophylla, secretes toxins, a phenomenon called negative allelopathy. For example, mammals such as deer and buffalo form protective herds because it's much easier for predators to attack a lone animal than a large group.

This question probably means "What is a random selection from a population?" If that is so, then the answer is this. In ecology, a population consists of all the organisms of a given species that live in a particular area. Random distribution is rare in nature as biotic factors, such as the interactions with neighboring individuals, and abiotic factors, such as climate or soil conditions, generally cause organisms to be either clustered or spread.
