Question

question 2 of 25
which component of the biosphere is an example of inorganic matter?

a. sugar
b. protein
c. carbohydrate
d. carbon dioxide

Explanation:

Inorganic matter typically lacks carbon - hydrogen (C - H) bonds in its basic structure (with some exceptions like carbonates). Sugar, protein, and carbohydrate are organic compounds as they contain C - H bonds and are made up of carbon - based molecules with hydrogen. Carbon dioxide ($CO_2$) does not have C - H bonds and is classified as inorganic.

Answer:

D. Carbon dioxide
