Any animal that is killed and eaten by another animal.
The geosphere has four subsystems called the lithosphere, hydrosphere, cryosphere, and atmosphere. Because these subsystems interact with each other and the biosphere, they work together to influence the climate, trigger geological processes, and affect life all over the Earth.
