Nitrogen gas in the air is converted into usable forms by soil bacteria through a process called nitrogen fixation. Plants then take up these forms of nitrogen from the soil. When organisms consume plants, they obtain nitrogen from the plants, and the nitrogen cycles through the food chain as organisms are consumed by other organisms.

When there is not enough nitrogen in the atmosphere for plants how do the plants get it?
Plants can obtain nitrogen from the soil through their roots. They form symbiotic relationships with nitrogen-fixing bacteria in the soil, which convert atmospheric nitrogen into a form that plants can use. Additionally, decaying organic matter in the soil releases nitrogen that plants can absorb.
What happens to the nitrogen compounds that are not absorb by the plants?
A number microbes in the soil, water and air transform these nitrogen compounds
Why do farmers grow leguminous crops between 2 other plants?
Farmers grow leguminous crops between other plants to improve soil fertility through nitrogen fixation. Legumes have a symbiotic relationship with nitrogen-fixing bacteria in their roots, which can enrich the soil with nitrogen that benefits neighboring plants. This practice is known as crop rotation and helps maintain soil health and productivity.
Why is nitrogenous fertilizer not added in soil in which leguminous plants are grown?
Because leguminous plants are capable of fixing free nitrogen from the air with help of their root nodules. Thus soil get rich in nitrates in those places where these plants are grown.
By what process is nitrogen returned to the atmosphere by bacteria?
Nitrogen is returned to the atmosphere by a process called denitrification, where certain bacteria convert nitrates in the soil back into nitrogen gas which is then released into the air. This helps maintain the balance of nitrogen in the environment cyclically.
What is the transfer of nitrogen from air to soil to organism and back to air or soil?
Nitrogen is transferred from the atmosphere to the soil through processes like nitrogen fixation by bacteria or lightning, where plants can uptake this nitrogen from the soil. Organisms then consume these plants, incorporating the nitrogen into their own tissues. When organisms die and decompose, nitrogen is released back into the soil, where it can be recycled back into the atmosphere as nitrogen gas through denitrification by bacteria, completing the nitrogen cycle.
What is the transfer of nitrogen from air to soil to organism and back to air and soil?
Nitrogen fixation by certain bacteria in soil converts atmospheric nitrogen into a form usable by plants. Plants take up nitrogen from soil through their roots, incorporating it into their tissues. When plants and animals die, decomposers break down their remains, releasing nitrogen back into the soil. Some nitrogen is also released back into the atmosphere through processes like denitrification.
Where can nitrogen be found besides the air?
in soil
What are the different ways by nitrogen in the air reaches the soil?
Nitrogen in the air reaches the soil primarily through a process called nitrogen fixation, where certain bacteria convert atmospheric nitrogen into a form that plants can use. Nitrogen can also reach the soil through precipitation, as nitrogen compounds are washed out of the atmosphere and deposited onto the soil surface. Additionally, nitrogen can enter the soil through the decomposition of organic matter, releasing nitrogen back into the soil as plant nutrients.
Which organism fix nitrogen in the soil?
Legumes such as clover, beans, and soybeans have symbiotic relationships with nitrogen-fixing bacteria like Rhizobium, allowing them to convert atmospheric nitrogen into a form that plants can use. These bacteria live in nodules on the plant's roots and help enrich the soil with available nitrogen.
What is the most common gas in soil air?
The most common gas in soil air is nitrogen, accounting for around 78% of the air in soil. Oxygen, carbon dioxide, and traces of other gases like argon and methane are also present in soil air.
The nitrogen cycle may be described as nitrogen moving from the air to the soil where plant roots use it as food. when plants die nitrogen is returned to the air true or false?
false, when the plant dies in this case, nitrogen is returned to the soil
Acid rain is caused by which of the following excess carbon dioxide deforestation nitrogen compounds in the air nitrogen compounds in the soil?

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.
Why are nitrogen bacteria contributes to the nitrogen cycle so important?

Which nitrogen in the air reaches the soil?
Nitrogen in the air reaches the soil primarily through a process called nitrogen fixation. Certain bacteria in the soil or associated with plant roots convert atmospheric nitrogen into a form that plants can use, such as ammonium or nitrate. These plants then assimilate the nitrogen into their tissues, which can later return to the soil through decomposition when the plants die.
How do humans and animals get nitrogen?
Nitrogen starts in soil and becomes useful nitrogen for plants and it gets passed on to animals. Decomposers would eat nitrogen-rich dead organisms and some of the nitrogen goes back into the soil.
