in the sandhills region of nebraska, a grassy prairie grows on sand dunes. the roots of grasses, such as the prairie sandreed, help hold the sand in place.
greater prairie chickens roam through the grasses eating seeds, leaves, and insects. adult prairie chickens are prey for coyotes, great horned owls, and red - tailed hawks. their eggs can be eaten by raccoons, skunks, and red foxes.
which of the following best describes an ecosystem on a prairie in nebraska?
the seeds, the leaves, and the insects
the red foxes
the sand dunes, the prairie sandreed, and the greater prairie chickens

Explanation:

An ecosystem includes all the living (biotic) and non - living (abiotic) components in a particular area. The sand dunes are non - living (abiotic), the prairie sandreed (a plant) and greater prairie chickens (an animal) are living (biotic). The first option (seeds, leaves, insects) only includes biotic components. The second option (red foxes) only includes one biotic component. The third option includes both biotic (prairie sandreed, greater prairie chickens) and abiotic (sand dunes) components which is what an ecosystem is made up of.

Answer:

the sand dunes, the prairie sandreed, and the greater prairie chickens
