Question:

Why is population ecology important?

Options:

Connects ecology with population genetics and evolution.

Focuses on the ability of individual organisms to adapt to a changing environment.

Studies the rates of birth and death of individual organisms.

Examines the characteristics and traits of individual organisms within a population.

Correct Answer:

Connects ecology with population genetics and evolution.

Explanation:

The correct answer is (a) Links ecology to population genetics and evolution.

Population ecology is an important field of study that focuses on understanding the dynamics and interactions of populations in relation to their environment. It examines the factors that influence population size, distribution, and structure, as well as the processes of birth, death, and migration within a population.

One of the key reasons why population ecology is important is that it provides a bridge between ecology and population genetics and evolution. It explores how ecological factors, such as resource availability, predation, and competition, shape the genetic composition of populations over time. It also investigates how genetic variations within populations can influence their ecological interactions and adaptations.

By integrating ecological principles with population genetics and evolutionary theory, population ecology helps us understand the mechanisms driving population changes, the emergence of new species, and the adaptation of populations to their changing environments. It provides valuable insights into the dynamics of biodiversity, species interactions, and the processes that shape the structure and functioning of ecosystems.

In summary, population ecology plays a crucial role in linking ecological processes to genetic and evolutionary dynamics, providing a comprehensive understanding of how populations of organisms interact with their environment and evolve over time.
