Detailed explanation-1: -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.

Detailed explanation-2: -A group of interacting populations forms a community. A community and its physical environment together form the ecosystem. When many ecosystems that are similar to each other interact with each other on a large scale, it is called a biome.

Detailed explanation-3: -A population is a group of individuals of the same species that live in the same geographic area that interbreed with each other. Many species consist of multiple populations dispersed over a few to many geographic areas.

Detailed explanation-4: -Zebras are social animals that live together in groups. They help the local ecosystem by grazing on dry, hardened grass that is too tough for other species (such as wildebeest, ostriches and antelopes) to digest.
