Detailed explanation-1: -By eating plants. You can obtain amino acids. So the answer for this problem will be auction be eating plants.

Detailed explanation-2: -Decomposition. Plants take up nitrogen compounds through their roots. Animals obtain these compounds when they eat the plants.

Detailed explanation-3: -Animals get these amino acids by eating plants or animals that eat plants. This works because plants can make all twenty amino acids including the ten or so “essential” ones that most animals can’t.

Detailed explanation-4: -Plants get the nitrogen that they need from the soil, where it has already been fixed by bacteria and archaea. Bacteria and archaea in the soil and in the roots of some plants have the ability to convert molecular nitrogen from the air (N2) to ammonia (NH3), thereby breaking the tough triple bond of molecular nitrogen.

Detailed explanation-5: -The nitrogen cycle matters because nitrogen is an essential nutrient for sustaining life on Earth. Nitrogen is a core component of amino acids, which are the building blocks of proteins, and of nucleic acids, which are the building blocks of genetic material (RNA and DNA).
