Question: 1 / 400

Which cycle is essential for organisms to make proteins?

Water Cycle

Carbon Cycle

Nitrogen Cycle

The nitrogen cycle is essential for organisms to make proteins because nitrogen is a key component of amino acids, which are the building blocks of proteins. Organisms require nitrogen in forms they can utilize, such as ammonia or nitrate. Through various processes in the nitrogen cycle, nitrogen is transformed from the atmosphere into forms that plants can uptake. Then, when animals consume these plants or other animals, they obtain the necessary nitrogen to synthesize proteins. This cycle ensures a continuous supply of nitrogen in forms that living organisms can incorporate into their biological processes, specifically protein synthesis.
