Question

read the passage. then answer the question below.
great sand dunes national park and preserve in colorado
the tallest sand dunes in north america are in colorado. in this desert region, the top few inches of sand are usually dry, but the lower layers remain moist year - round.
ords kangaroo rats spend their entire lives in these dunes. they collect seeds from grasses and prairie sunflowers, and then bury the seeds in the moist layers of sand. later, the rats come back to eat their buried seeds. the seeds absorb enough moisture from the sand that the kangaroo rats never need to drink water!
which of the following best describes a community in the great sand dunes?
the ords kangaroo rats
the grasses and the prairie sunflowers
the grasses, the water, and the sand dunes

Explanation:

A community in ecology consists of different populations of organisms living together. The Ord's kangaroo rats are one population, grasses and prairie sunflowers are plant populations. The third option includes non - living components (water, sand dunes) which are part of the ecosystem, not the community. Among the first two, the grasses and prairie sunflowers represent different plant populations in the same area, forming a community. The Ord's kangaroo rats are a single population.

Answer:

the grasses and the prairie sunflowers
