Which of the following steps of the nitrogen cycle is pictured?

Which of the following is NOT a process that drives the carbon cycle?

Briefly explain why the water cycle is important to the biosphere.

Briefly explain why the carbon cycle is important to the biosphere.

Briefly explain why the nitrogen cycle is important to the biosphere.

Importance of water cycle: Water cycle is very necessary for the survival of organisms. Water is used by the plants as a raw material and used for the production of food. This food is eaten by other animals.

Importance of carbon cycle: Carbon is used by the plants in the form of carbondioxide in the process of photosynthesis. Food materials also contain carbon. So carbon is very important for biosphere.

Importance of nitrogen cycle: Nitrogen is important for the plants. When water falls from the sky, the nitrogen also comes to the earth surface. This nitrogen is used by the plants through the roots. This nitrogen helps the plant grow quickly and made maximum vegetation cover and provide food for many organisms.
