Final answer:
The organization of the biosphere can be explained by the (option C)Groups of individuals make up populations, and groups of populations make up communities.
Step-by-step explanation:
The organization of the biosphere can be best explained by the statement: (option C)Groups of individuals make up populations, and groups of populations make up communities. In biology, a population refers to all the individuals of a single species living in a specific area. A community, on the other hand, includes all the populations of different species living in a particular area. Therefore, populations make up communities, while communities make up ecosystems and eventually, groups of ecosystems make up the biosphere.
