Animals use oxygen to convert this food into energy they can use, and to maintain a steady supply of carbon atoms that are necessary for building any animal cells. Respiration also returns carbon dioxide back to the atmosphere as a waste product, where plants can reabsorb it in the process of photosynthesis. hope I helped.

Answer:
Red.
Explanation:
- Methyl orange is an organic dye that used as an indicator in acid-base titrations because its color is changed according to the pH of the medium (acidic, neutral or basic).
- Methyl orange is red in acidic solutions, orange in neutral solutions, and yellow in basic solutions.
<em>Since, pH of the solution is 2, the solution is acidic, the color of the solution will be red.</em>
