<u>Explanation:
</u>
- The biosphere includes all the living organisms on the planet
- The biosphere is a global ecological system that forms the layer of the earth where life exists.
- The layers of earth that form the biosphere are lithosphere (rock), hydrosphere (water) and atmosphere (air) which together known as an ecosystem.
- Biosphere acts as a self-supporting and self-regulating system were the remaining of the dead plants and animals are released into soil and ocean thus, in turn, it is reabsorbed by plants for growing.
- The biosphere sometimes is one large ecosystem that is comprised of a complex community of living and nonliving things functioning as a single unit.
Don't quote me on it but I believe the first one was Democritus in the time of Ancient Greece. At the time he had no evidence though, just a lucky guess made by him.
