Question

Describe the different steps in the nitrogen cycle...Only according to the above image...Plz teach me this.....​

Answer 1

Answer:

The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. 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,[16] making it the largest source of nitrogen. However, atmospheric nitrogen has limited availability for biological use, leading to a scarcity of usable nitrogen in many types of ecosystems.

Explanation:

In general, the nitrogen cycle has five steps:

• Nitrogen fixation (N2 to NH3/ NH4+ or NO3-)
• Nitrification (NH3 to NO3-)
• Assimilation (Incorporation of NH3 and NO3- into biological tissues)
• Ammonification (organic nitrogen compounds to NH3)
• Denitrification(NO3- to N2)
