Plants take nitrogen in the form of nitrates. The atmospheric nitrogen is first converted into ammonia after that ammonia is converted into nitrates and this nitrates use by the plants to make proteins.

<span>Apart from their habitats, Bacteria and Archaea differ in cell wall structure and membrane lipid composition. All bacteria have peptidoglycans in the cell wall whereas the archaea do not. Both also are different in RNA polymerases and thus in their protein synthesis. </span>
A cladogram is similar to Family Tree
Explanation:
A cladogram and a family tree both show relationships between common ancestors. It shows the relationship the organism but it is not same as evolutionary or family tree because it doesn’t show the relationship with ancestor to their descendent and also it doesn’t show how they changed.
