How Is The Amniotic Egg A Benefit To Land Animals?

The amniotic egg allowed tetrapods to become completely terrestrial. In an amniotic egg, a membrane called the amnion surrounds the embryo and creates a fluid-filled cavity in which it develops. Other membranes aid in gas exchange, protection, and removal of wastes.[15]

Why Do Aquatic Animals, Mammals, And Reptiles Secrete Nitrogenous Wastes In Different Forms?

Why Do Different Animals Excrete Different Nitrogenous Wastes?

Animals excrete a variety of nitrogen waste products, but ammonia, urea and uric acid predominate. A major factor in determining the mode of nitrogen excretion is the availability of water in the environment.[17]

How Is Reptile Nitrogen Excretion Different From Mammal Excretion?

Nitrogenous wastes in the body tend to form toxic ammonia, which must be excreted. Mammals such as humans excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste. Uricothelic organisms tend to excrete uric acid waste in the form of a white paste or powder.Jun 8, 2022[18]
