Consider the following:
a. Biosphere
b. Atmosphere
c. Hydrosphere
d. Evolution of Life
How many of the above maintain homeostasis on Earth?
Correct
The answer is c.
All four, Biosphere, Atmosphere, Hydrosphere and Evolution of Life maintain homeostasis on Earth. Ecosystem homeostasis is equilibrium or a balance of the organisms in an ecosystem. This means the populations of species in the ecosystem are relatively stable. Over time, these populations will change, but in the short term, they should move up and down in cycles around an average value
