Animals obtain their nitrogen from?

Answer 1

Animals obtain their nitrogen primarily through their diet. They consume plants or other animals that contain proteins, which are composed of amino acids containing nitrogen. This nitrogen is incorporated into the animal's own proteins and other nitrogen-containing compounds. Some animals, such as carnivores, obtain their nitrogen directly from consuming other animals, while others, such as herbivores, obtain nitrogen indirectly by consuming plants. In addition to dietary sources, animals can also obtain nitrogen from the breakdown of their own proteins during metabolism.
