Final answer:
The correct answer is b. population, which refers to a group of organisms of the same species living in a specific location.
Step-by-step explanation:
A group of organisms of the same species that live in a specific location is called a population. This biological term refers to the collection of individuals belonging to the same species that share the same geographical area and have the potential to interbreed. For instance, a group of white pine trees living in the same forest area would be considered a population of white pine trees.
In contrast, a community includes all the different populations of various species that live in the same area and interact with each other. This includes all the biotic, or living, components of the ecosystem. Ecosystems, which are broader concepts, include both the living (biotic) and non-living (abiotic) factors of the environment.
Therefore, the correct answer to the given question is b. population.
