Question

read the passage. then answer the question below.
white - bearded wildebeests on the serengeti plains
on the serengeti plains in eastern africa, umbrella acacia trees are scattered among many species of grasses that grow together. the grasses grow well because the soil has a lot of nutrients.
the plains are home to many species of herbivores, such as burchell’s zebras, northern black rhinoceros, and white - bearded wildebeests. one reason so many species of herbivores can live together is that each species prefers to eat a different kind of plant.
which of the following best describes a community on the serengeti plains?
the burchell’s zebras, the northern black rhinoceros, and the white - bearded wildebeests
the umbrella acacia trees

Explanation:

To determine the correct answer, we first recall the definition of a biological community: a community consists of all the different populations of species that live and interact in a particular area.

Analyzing the options:

1. "the Burchell’s zebras, the northern black rhinoceros, and the white - bearded wildebeests": This option includes multiple different species (populations) of herbivores that live on the Serengeti plains. These different species interact with each other and with the other organisms (like plants) in the area, so this group can be considered a part of the community (or represents the animal - part of the community) on the Serengeti plains.
2. "the umbrella acacia trees": This is just a single population of a single species (the umbrella acacia trees). A single population of one species does not represent a community, as a community needs multiple different species.

Answer:

the Burchell’s zebras, the northern black rhinoceros, and the white - bearded wildebeests
