Explanation:

A community in an ecosystem consists of all the populations of different species that live and interact in a particular area. The first option includes non - living elements (water, sand dunes), which are part of the environment but not the community. The second option is just one species (Ord's kangaroo rats), not a community. The third option includes two different plant species (grasses and prairie sunflowers), which is a group of different species and thus represents a community.

Answer:

the grasses and the prairie sunflowers
