Answer 1

Water cycle, carbon-oxygen cycle, and nitrogen cycle are essential components of life that pass through organisms.

Answer 2

Answer: Water cycle, Nitrogen cycle, Carbon oxygen cycle

Water cycle: The water cycle is very important because it provides water to all the approximately all the regions of the earth, to all living organisms and regulates the weather pattern. The water gets evaporated from the water bodies in hot humid climatic conditions and gets condensed in the form of rain or any other precipitation keeps the environment cool necessary for the survival of the living organisms.

Nitrogen cycle: Nitrogen gas of around 78% present in the earth atmosphere. This gas is absorbed by the soil microbes and transferred to the plants. This helps in the development and growth of the plants. The plants are consumed by animals and humans. The organic matter generated after the decomposition process of the dead organisms is a product of organic nitrogen preserved in the soil.

Carbon oxygen cycle: The carbon dioxide is a gas that is present in the earth atmosphere. It is obtained by the plants to prepare their own food in the form of carbohydrates and released oxygen into the atmosphere. This oxygen is taken by the other living organisms such as animals, humans and microbes and they release carbon dioxide back into the atmosphere which is again taken up by the plants for conducting photosynthesis.
