Please send an easy flow chart of water cycle and nitrogen cycle

In the atmosphere, the concentration of nitrogen is about 78%. It is essential for plants. Nitrogen forms a structural component of many important molecules such as DNA, RNA, and other vitamins. Plants cannot absorb nitrogen from the atmosphere. Certain forms of bacteria are able to convert atmospheric nitrogen into usable forms such as nitrates and nitrites. Such nitrogen fixing bacteria are commonly found in the roots of legumes (plants of pulses) inside special structures called root nodules. These usable forms of nitrogen are absorbed by plants to produce many compounds such as amino acids, which in turn form proteins. When an animal feeds on plants, nitrogen enters its body.When plants and animals die, they start decomposing after some time. During this process, proteins are converted into nitrates and nitrites by the action of decomposing bacteria. Certain other forms of bacteria convert nitrates and nitrites into elemental nitrogen. Thus, nitrogen flows between the various components of the biosphere in a cyclical manner. There are basically 5 steps of nitrogen cycle that help in fixing atmospheric nitrogen:

• Nitrogen Fixation (N₂to NO₃- or NH₄)
• Nitrification (NH₃to NO₃- )
• Assimiliation (here the NH₃and NO₃- are incorporated into the biological tissues)
• Ammonification (organic nitrogen compounds to NH₃)
• Denitrification (NO₃- to N₂)

Recycling of nitrogen in the environment

Water cycle:
 

Water undergoes different processes in the environment and is found in different states during these processes. This cyclic process through which water circulates in the environment is called the water cycle. There are four main steps involved in water cycle

1) Evaporation

2) Condensation

3) Precipitation

4) Run off

Evaporation is the process through which water is converted into water vapour. Heat or sunlight converts water into water vapour. Water is also emitted from the leaves of the plants through the process of transpiration.

This water vapour in the atmosphere condenses to form clouds through the process ofcondensation.

When enough water is condensed to form clouds, it falls down on the surface of the Earth in the form of rain, snow, hail, etc. This process is known as precipitation.

The water that falls down as precipitation runs through the rivers and seeps underground. It also flows off the surface as surface run off to join low-lying water bodies. In this manner, water is circulated in the environment.
