African lungfish, which are often found in small, stagnant pools of fresh water, produce urea as a nitrogenous waste. What is the advantage of this adaptation?

a) urea takes less energy to synthesize than ammonia.

b) small stangnant pools do not provide enough water to dilute the toxic ammonia.

c) the highlt toxic urea makes the pool uninhabitable to potential competitors.

Answer:b) small stangnant pools do not provide enough water

Explanation:

African lungfish is obligate and fresh water habitat organism.

It aestivates between raining season During this peroid it produces UREA which is non toxic and stores iin the body to be excreted into water on the return of wet seasons.

Therefore, if it produces Ammonia, during Aestivation; ammonia is posinious and this kills the lungfish during aestivation of no water and oxygen supply.
