The biosphere of the earth is made up of . a. inorganic b. organic

B.

Explanation:

When we say "biosphere", we're referring to the atmosphere, geosphere, lithosphere and hydrosphere, and everything in them. You've probably heard of these in class as the "pillars of Earth" or the "pillars of our planet". In other words, when we talk about biosphere we're talking about life.

Organic compounds are all of the compounds that contain carbon, C, in them. You might know that CHNOPS* are the "7 molecules of life", and you might have noticed that Carbon stands first in the list, and that's not because it makes up a mnemonic, Carbon is indeed the most important one in many ways.

*Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus and Sulfur.
