The correct answer is 'population.' All the ants in an anthill make up a population. A population consists of individuals of the same species living in a particular area. An ecosystem includes all the living things (plants, animals, and organisms) in a given area, interacting with each other and their environment. A habitat is the natural environment where an organism lives. A community consists of all the different populations that live together in a particular area.
