Nutrient Cycle in the Ecosystem

What is the meaning of Nutrient Cycle in the Ecosystem?

1) Phosphorus cycle

2) Carbon cycle

3) Nitrogen Cycle

Answer:

1) Phosphorus cycle

Living organisms are composed of essential biomolecules like carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus. These nutrients are cycled between living things and the soil in what is known as the nutrient cycle. Plants absorb these nutrients from the soil and turn them into organic compounds through assimilation. Animals then eat the plants and pass the nutrients through the food chain from one organism to another. When the animal dies, it decomposes and returns the nutrients back to the soil, completing the cycle.

The phosphorus cycle, also known as the biogeochemical cycle, plays a crucial role in the ecosystem. Nutrient cycles ensure that essential elements are continuously recycled in an ecosystem, supporting the growth and sustainability of life.
