Question

Earthworm is _____________.

• A. Ureotelic
• B. Ammoneotelic
• C. Uricotelic
• D. Both (1) and (2)

Answer 1

The correct option is D Both (1) and (2)

Earthworms are both ureotelic and ammonotelic. An earthworm excretes the nitrogenous wastes in the form of urea, water, traces of ammonia and creatinine. Nephridia excrete these substances from the body of an earthworm. They are ammonotelic when sufficient water is available and ureotelic when water availability is reduced.

So, the correct option is 'Both (1) and (2)'.
