All plants and animals need nitrogen to make amino acids, proteins and DNA, but the nitrogen in the atmosphere is not in a form that they can use. The molecules of nitrogen in the atmosphere can become usable for living things when they are broken apart during lightning strikes or fires, by certain types of bacteria, or by bacteria associated with legume plants. Other plants get the nitrogen they need from the soils or water in which they live mostly in the form of inorganic nitrate (NO3-). Nitrogen is a limiting factor for plant growth.

Nitrates are important to make amino acids. The amino acids could then be joined together to form proteins.

Without it, the growth of the plant will be slowed down and the leafs will droop down.

Hope this helps! :D

Nitrates are absorbed by plants in ion form and its nitrogen is used in protein synthesis

Why are nitrogen-fixing bacteria important to plants?

nitrogen fixing bacteria fix or attach atmospheric nitrogen in soil or make it easily avialable to the plants as plants need nitrogen as one of their macronutrient element for their growth.


Why are nitrogen-fixing bacteria contributions to the nitrogen cycle important?

The air is about 80% nitrogen- but cannot be used by plants for food. Nitrogen fixing bacteria transform nitrogen in the air to nitrogen in the soil that plants CAN use- resulting in greatly improved plant growth, and more fertile soil.
