It gives the earth much needed heat and light.
It provides the earth with available water for organisms.
It supplies the earth with enough gases in the atmosphere.
How does diversity of life become an important factor in our existence?
It makes the populations grow without limits.
It enables organisms to reproduce its own kind.
It makes ecosystems thrive with the population of producers.
It makes ecosystems productive with the roles that each species plays.
Earth is considered a habitable planet because it is situated in what we refer to as the "habitable zone" within the solar system. What do you think would happen if Earth were located farther than this habitable zone?
The Earth will become a ball of fire.
The Earth will become an ice-coated rock.
Fewer organisms will thrive due to the rise in Earth's temperature.
More organisms will thrive due to the decrease in Earth's temperature.
How is biosphere affected by all other Earth’s subsystem?
