Mam I have a doubt that we can fulfil protein(nitrogenous compound) need by eating eggs and other proteins foods so there is no need to eat leguminous plant based foods. Then, no need to do such a long process of nitrogen fixation and it’s cycle

[@MagnetBrainsEducation]

Thanks for your comment! Eating foods that are high in protein is a great way to fulfill your protein needs, and eggs are high in protein. However, leguminous plants also provide essential nutrients that are not found in other foods, and their nitrogen-fixing capabilities make them an important part of the global nitrogen cycle. We recommend incorporating both types of food into your diet for a balanced and healthy lifestyle.

Is lightning process is always happening during nitrogen fixation?

[@MagnetBrainsEducation]

Thanks for your question! The answer is no. Light fixation is a process by which organisms use light energy to produce carbohydrates from carbon dioxide. On the other hand, nitrogen fixation is a process in which organisms convert atmospheric nitrogen into a form that can be used by living beings.

I have a doubt that if lightning process was done then there is no need to do nitrogen fixation ?

[@MagnetBrainsEducation]

Hi there! Thanks for your comment! Nitrogen fixation is an important process and lightning can contribute to it, but it is not solely responsible for it. Nitrogen fixation is a process that occurs in nature primarily through bacteria and archaea, both of which have important roles within ecosystems. Lightning is one way that can help in nitrogen fixation by providing energy for the process, but it is not a replacement for the biological process. Hope this helps!
