Question

Biotic and abiotic factors affect population density and dispersion. A) Explain the factors that affect a population's density. B) Describe the types of population dispersion, with examples, and the factors that influence them.

Answer 1

Water supply, climate, shape of the land, vegetation, soils and availability of natural resources.

Step-by-step explanation:

Water supply, climate, shape of the land, vegetation, soils and availability of natural resources are the factors that affect population density of an ecosystem. There are three types of population dispersion are uniform dispersion, random dispersion, and clumped dispersion. In uniform dispersion, individuals of a population are more or less evenly distributed for example, allelopathy plants. In random dispersion, individuals are distributed randomly in the ecosystem for example, dandelions plants. Clumped dispersion is when individuals in a population are clustered together for example, oak trees.
