Question

Differeniate the ureotelic and uricotelic animals

Answer 1

Explanation:

A ureotelic organism excretes excess nitrogen as urea. Urea is less toxic and needs less water in comparison to Ammonia. Ureotelic organisms include cartilaginous fish, few bony fishes, adult amphibians and mammals including humans. The uricotelic organism excretes uric acid or its salts.....

hope it will be helpful for u ❤☺❤☺

Answer 2

Ureotelic animals

• A ureotelic organism excretes excess nitrogen as urea.
• Urea is less toxic and needs less water in comparison to Ammonia.
• The uricotelic organism excretes uric acid or its salts.
• In contrast to Ammonia and Urea, Uric acid is the least toxic and the most limited soluble in water.
• It can be stored in cells and body tissues without toxic effects and thus needs the least water and is a highly efficient mode of excretion in comparison to two other methods.

Example

• Ureotelic organisms include cartilaginous fish, few bony fishes, adult amphibians and mammals including humans.

Uricotelic animals

• The species that excrete uric acid waste are called uricotelic organisms.
• The excreta of uricotelic organisms is typically white paste and insoluble solids or semi-solid.
• Needs very little water just to flush out the uric acid

Example

• Uricotelic organisms include terrestrial arthropods (including insects), lizards, snakes, and birds.
