Question

robert says that in population ecology, a population is the total number of organisms that belong to a single species. arjun correctly points out that the term is more often used to describe a smaller group of organisms. what is the most common definition of a population? a. all organisms are playing the same role in an ecosystem b. all organisms that are native to a given area c. all members of a species that form a group, such as a pod or school d. all members of a species that are living in a given area

Explanation:

In population ecology, a population is defined as all members of a species living in a specific area. Option A refers to a functional role (not population). Option B includes all native organisms (multiple species). Option C refers to a group within a species but not the population definition. Option D aligns with the standard population - definition (species + given area).

Answer:

D. all members of a species that are living in a given area
