Question

An ecology research project aims to understand how reducing habitat size impacts extinction rates of a beetle species. Relevant data include the number of beetles that are captured over time in habitats of different sizes. This question focuses on what subfield of ecology?

Answer 1

population ecology.

Step-by-step explanation:

Population ecology is a subfield of ecology in which the ecologists study various aspects of ecology such as habitat, temperature or other environmental factors which are responsible for the increase or decrease in the population of particular specie. In this subfield of ecology, we study that how is the population changes over time and why the population changes with the passage of time or what factors are responsible for this change.

Answer 2

ANSWER: POPULATION ECOLOGY

EXPLANATION:

The scientific field that deals with populations (i.e all individuals of a single species inhabiting a community) and how they interact with their extrinsic environment, is referred to as POPULATION ECOLOGY.

Thus, it's categorized under population ecology, because the research depicts how the number of individuals (beetles) in a population changes in time and the gross impact on their number decrease and loss of all the individuals (extinction) over a period of time.
