Population, community, biome, and habitats
A population is a group of living organisms of the same kind living in the same place at the same time. A community is two or more species living together in one place. Biomes are large regions of the world with similar plants, animals, and other living things that are adapted to the climate and other conditions.
Bears have habitats all over the world. They can be in hot or cold places, but all of the Bears habitats are affected. They are affected by us humans. By us affecting their habitats, bears have to move constantly to find new homes.
