Infer how an organism, like a polar bear, might interact with each of earth's 5 spheres.

The five earth's spheres are biosphere, hydrosphere, atmosphere, geosphere and lithosphere.

An organism like polar bear might react with each of the sphere in the following way: The bear has its habitat on the land (lithosphere), he eat grasses and other small animals found in the biosphere. It drinks water, which is part of the hydrosphere. It breaths in oxygen and breath out carbon dioxide into the atmosphere. Its wastes is a source of food to decomposers, (in the geosphere) which breaks it down for plants' use
