Question

Why ammonia is not directly excrete out in terrestial animal?

Answer 1

In animals, the main excretory products are carbon dioxide, ammonia (inammoniotelics), urea (in ureotelics), uric acid (in uricotelics), guanine (inArachnida) and creatine. The liver and kidneys clear many substances from the blood (for example, in renal excretion), and the cleared substances are then excreted from the body in theurine and feces.

Answer 2

ammonia is not directly excreted out in terrestrial animals because ammonia is so poisonous to the cells and requires a lot of water to flush it out in terrestrial animals.

hope this helps you :-)
