Which of the earth’s spheres is made up of all living things? a. the atmosphere b. the biosphere c. the lithosphere d. the hydrosphere

The biosphere, or B.

The atmosphere is basically the air, sky, clouds, etc.

The hydrosphere is made up of bodies of water like oceans, lakes, etc.

The lithosphere, if I remember correctly, is made up by the upper mantle and crust of the earth.

The "bio" in "biosphere" means life. It's the sphere made up of all living things. So the correct answer should be B! :)
