Final answer:
Each option represents a population, as they all consist of groups of the same species living and breeding in a specific area. This includes a pack of wolves, a herd of elephants, a school of fish, and a colony of ants.
Step-by-step explanation:
A population is defined in biology as a group of organisms belonging to the same species that live in a particular area and are capable of interbreeding. The concept of population applies to various species, including humans, animals, and plants. Therefore, each option given in the student's question can be considered a population because they all represent groups of the same species living together in a specific area. Specifically, a pack of wolves consists of conspecifics that interact and potentially breed within their group. Similarly, a herd of elephants represents a population of elephants living and interacting in the same region. A school of fish, made up of members of the same species living in the same part of the ocean, is another good example of a population. Lastly, a colony of ants, which includes interbreeding individuals of the same species cohabitating in a well-defined area, also forms a population.
