Question

explain the carbon cycle , nitrogen cycle and oxygen cycle​

Answer 1

Explanation:

Nitrogen cycle:- the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.

Carbon cycle:- The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone.

Oxygen cycle:- The Oxygen cycle is the biogeochemical cycle that describes the movement of oxygen within and between its three main reservoirs: the atmosphere (air), the total content of biological matter within the biosphere (the global sum of all ecosystems), and the lithosphere (Earth's crust).

Answer 2

Oxygen cycle: It is a continuous process which revolves around the living organism plant which plays a great role in this.As plant inhale CO2 which we exhale and in return it exhales O2. So this process continues the Oxygen cycle.

Nitrogen cycle:The conversion of nitrogen can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification. The majority of Earth's atmosphere (78%) is atmosphere nitrogen. However, atmospheric nitrogen has limited availability for biological use, leading to a scarcity of usable nitrogen in many types of ecosystems.

Water cycle: The continuous recharging of water in the atmosphere of earth by the contributions of all water bodies such as river,ponds,lake & ocean which changes into the vapour by the change of evaporation which brings it to form of clouds which later on precipitates.
