Question

Which of the following is not accumulated by the body of living organisms?

• A. Ammonia
• B. Carbon dioxide
• C. Urea
• D. Oxygen

Answer 1

Answer:

D. Oxygen

• Oxygen is not accumulated by the body of living organisms as this is required by the cells to perform respiration.

• Also, it is not a waste product of the cells. Animals accumulate ammonia, urea, uric acid, carbon dioxide, water, and ions like Na+, K+, Cl–, phosphate, sulphate, etc., by certain metabolic activities.
