2. Urea, a nitrogenous waste product, is excreted by ureotelic organisms.
3. Uricotelic organisms produce uric acid, a nitrogenous waste product.
4. Excretion in sponges is primarily accomplished through diffusion across the body surface.
5. Sponge excretion is mostly ammonia, so they are ammonotelic.
