Question

What is population ecology and why is it important?

Answer 1

The study of spatial and temporal patterns in the abundance and distribution of organisms and of the mechanisms that produce those patterns.

Explanation:

Population ecology also studies the ethological structure of a population. This structure reflects the nature of a population’s organization and is expressed by various associations of individuals, such as families, flocks, herds, and colonies among animals, colonies among microorganisms and lower plants, and groups of trees or shrubs and clumps of grasses among higher plants.

These associations ensure propagation, systematic use of the territory and its resources, and mutual help and protection against enemies and unfavorable conditions.
