Question

A herd of zebra eating grass includes groups of organisms from different species. These groups best exemplify. A. a biome interaction. B. a community interaction. C. an ecosystem interaction. D. a population interaction.

Answer 1

The answer is
B. A community

Answer 2

The answer is B. a community interaction.

Let's distinguish some terms:
A population is a group of organisms of the same species in an area. If there were a herd of only zebras, this would be a population interaction.

A community is a group of organisms from different species in an area. A herd of zebra eating grass includes groups of organisms from different species is an example of a community interaction.

An ecosystem consists of all organisms (from different species) in an area and their physical environment.

A biome is a large area defined by abiotic factors.
