Which one of the following option is incorrect about excretory system of animals?
The major excretary product in lizards is urea.
Fishes live in water and excrete their nitrogenous waste mainly as ammonia, which is highly soluble and readily dissolves in the surrounding water, so this statement is true.
Birds need to conserve water and reduce body weight for flight, so they excrete a semi-solid, paste-like waste that is rich in uric acid, so this statement is true.
Lizards, like birds, are adapted to conserve water and excrete their nitrogenous waste mainly as uric acid in a semi-solid form, not as urea, so the statement that their major excretory product is urea is incorrect.
Humans excrete nitrogenous waste mainly as urea dissolved in water, along with other semi-solid components, so this statement is true.
Hence, the incorrect statement is that the major excretory product in lizards is urea, since lizards actually excrete uric acid.
