What is nitrogen fixation and why are bacteria crucial to this cycle of life?

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.

The cycle of nature, is a cycle of energy. Bacteria, the Monera Kigdom in this aspect regenearte energy and re introduce dead organims energy into the system of nature's matrix.

Bacteria are cructial in this cycle because it is bacteria that carry of this fixation.

What are the 3 stages of the nitrogen Cycle?
Nitrogen fixation,Denitrification and nitrification
What are the different cycles in nature?
A payroll cycle is the determined period of time of allocated hours worked.
7. Which cycle does not have a gaseous phase?
nitrogen cycle
Describe why nitrogen must cycle through an ecosystem?
Nitrogen must be cycled through an ecosystem so that the nitrogen is available for organisms to make proteins.
What are some examples of periodic cycles?
water cycle, rock cycle, carbon dioxide/oxygen cycle, nitrogen cycle
Cycle which is dependent on bacteria for nitrogen fixation and denitrifcation?
the nitrogen cycle...
What cycle depends on the bacteria in these nodules?
Then cycle that depends on bacteria to convert nitrogen gas into ammonia is the nitrogen cycle. This is the part of the cycle called nitrogen fixation.
What procces happens in the nitrogen cycle requiring microorganisms or bacteria?
Nitrogen fixation.
What processes in the nitrogen cycle are completed by bacteria?
It is nitrogen fixation, which occurs by nitrogen-fixing bacteria that live in the root nodules of legumes and in the soil..
Why are bacteria required in nitrogen cycle?
Nitrogen needs to be fixed before it is used by plants.
The conversion of nitrates to nitrogen gas by bacteria is called?
Nitrogen Fixation.
What are methods of nitrogen fixation that complete the nitrogen cycle?
nitrogen fixation takes place with the help of lightning , bacteria called rhizobium lives in the nodules of legumenous plants convert nitrogen into nitrogeous compounds , algae etc. also helps in nitrogen fixation
Bacteria return nitrogen to the soil by which process?
The role of bacteria in the Nitrogen Cycle is to perform biological nitrogen fixation. This process is an important part of the Nitrogen Cycle because it converts oxygen into ammonia that plants are then able to use.
What cycle does not cycle in the atmosphere?
What is nitrogen fixation
What is the process in the nitrogen cycle by which plant roots absorb nitrates?
assimilation
What is the first step of the nitrogen cycle?
The first step of the nitrogen cycle is nitrogen fixation.
Is the first step of the nitrogen cycle?
The first step of the nitrogen cycle is nitrogen fixation.
