Question

Define the five systems in a Biosphere . Be sure to include enough information to distinguish each system from the others.

Answer 1

The Biosphere is the zone of earth, land and air where life exists. It is a complex multilayered system that is typically broken up into 3 (not 5) distinct components. These are:

1. Lithosphere -this is essentially the land (the solid component of earth).

2. Hydrosphere - the watery parts of the earths surface including oceans, lakes, pools.

3. Atmosphere - the gas component enveloping earth supporting life, including the lower atmosphere and gases such oxygen, carbon dioxide, nitrogen.
