NEET BIOLOGY

Detailed explanation-1: -Animal excretion Feces (poop) is not part of excretion because this does not come from chemical reactions inside cells. Instead feces are the parts of food that never got digested and sent to the cells of the body.

Detailed explanation-2: -Excretion is the physiological process of elimination of metabolic waste from the body. The excretory products include amino acids, urea, uric acid, carbon dioxide, water, and ammonia. Some Molluscs and Echinoderms excrete waste products from the body in the form of amino acids.

Detailed explanation-3: -Carbon dioxide, urea and water are excreted from the body in one way or the other. Removal of undigested food through the anus is not excretion. This process is called defecation.

Detailed explanation-4: -excretion, the process by which animals rid themselves of waste products and of the nitrogenous by-products of metabolism. Through excretion organisms control osmotic pressure-the balance between inorganic ions and water-and maintain acid-base balance.
