Question

Which animal conserves water through the excretion process?

• A. Camel
• B. Kangaroo rat
• C. Frog
• D. Fish

Hint:

Animals living in deserts have physiological adaptations like efficient kidneys and metabolic water production to survive extreme conditions.

Answer 1

The Correct Option is B

Kangaroo rats are desert-dwelling animals that conserve water through the following adaptations:
They produce highly concentrated urine to minimize water loss.
Water is reabsorbed efficiently in their kidneys, reducing water loss through excretion.
They obtain water primarily through metabolic processes (metabolic water) rather than drinking free water.
They produce dry feces, which further minimizes water loss.
These adaptations are critical for survival in arid environments where water is scarce.
Final Answer: \[ \boxed{\text{Kangaroo rat}} \]
