<u>Answer:</u>
<em>lightening breaks</em><em> down the nitrogen molecules and provide a suitable environment to mix with oxygen (high temperature and pressure). </em>
<em>When these mix with water, the nitric acids are obtained which dissolves in soil and plants can use those </em><em>nitric acids for growth and development.</em>
<u>Explanation:</u>
The role of bacteria in nitrogen cycle is it breaks down the protein content in <em>dead plants and animals during decay process</em> and ammonia is formed.
Then the<em> nitrifying bacteria causes nitrification</em> which turns nitrogen into soluble nitrates that the plants can absorb.
