Where does all life exist???

Question

i got this question for h/w and it seems like the biosphere but what about the hydrosphere??? are fish not considered life???

so clarification appreciated

Answer 1

Biosphere: Portion of the earth inhabited by life: sum of all ecosystems. This area is a relatively thin layer of seas, lakes, streams, land to soil depth of a few meters, and atmosphere to an altitude of a few kilometers.

Answer 2

Yes, it is the Biosphere. Biosphere consists of Lithosphere and Hydrosphere, which simply means that it is a larger unit. Lithosphere is the land region where all the terrestrial biota lives whereas Hydrosphere consists of all the water bodies and all the flora and fauna living therein. Both these spheres combine to form the Biosphere which means the sphere where life exists.

Answer 3

I think "biosphere" simply means "the place where all life exists" - including land, water, and air. "Hydrosphere", I believe, simply means "the place where water exists". So... the biosphere should include parts of the hydrosphere, and so fish would be included.

Hope this helps.

Answer 4

Life is like water, it exists everywhere it can. Scientists have found life thriving in all kinds of conditions everywhere on the planet, from the darkest depths of the ocean to miles and miles underground. Life is common material of the universe I believe.
