Concept:In ecology, organisms are grouped into different levels such as population, community, and ecosystem based on species and area.
Explanation:A population is a group of organisms that belong to the same species and live together in a particular geographical area at the same time.
This matches the description given in the question exactly.
A colony refers to organisms of the same species living together, but it usually implies physical association or interdependence between individuals.
An ecosystem includes all living organisms in an area together with non-living components such as air, water, and soil.
A niche describes the specific role or position of an organism within its environment, not a group of organisms.
Therefore, the term that correctly defines a group of the same species in a particular place is population.
Answer:D. population
