Answer 1

D) is right answer.

Answer 2

Oxygen is required for cellular respiration and is used to break down nutrients, like sugar, to generate ATP (energy) and carbon dioxide and water (waste). Organisms from all kingdoms of life, including bacteria, archaea, plants, protists, animals, and fungi, can use cellular respiration.
