What else can I help you with?
The term nitrogen fixation refers to the?
biological process where certain microorganisms convert atmospheric nitrogen into forms that plants can use for growth, such as ammonia or nitrate. This process is essential for maintaining soil fertility and the overall nitrogen cycle in ecosystems.
What is the role of microorganisms in returning nitrogen or carbon dioxide to the atmosphere?
this microorganisms is called denitrifying bacteria, it helps to decompose the nutrients (nitrogen) back to the atmosphere. and the process of returning nitrogen or carbon dioxide to the atmosphere is called denitrification.
What is the use of microorganisms in the nitrogen cycle?
Microorganisms play a key role in the nitrogen cycle by converting nitrogen from the atmosphere into forms that can be used by plants. This process, known as nitrogen fixation, is carried out by nitrogen-fixing bacteria. Other microorganisms, like nitrifying bacteria and denitrifying bacteria, are involved in converting nitrogen compounds into different forms throughout the cycle.
How is the nitrogen cycle affected by desertification?
In the case of nitrogen-fixating bacteria or other microorganisms living in symbiosis with plants, if plants are removed so too will the microorganisms.
Does the nitrogen cycle has no atmospheric component?
It definitely does have an atmospheric component. When organic material is decomposed some of the microorganisms involved in doing this, called denitrifying bacteria, extract the nitrogen from the organic material and put it back in the atmosphere. Other bacteria take nitrogen from the atmosphere and convert it into substances that plants can use. Thus the atmosphere serves as an enormous pool of nitrogen for life. Please see the wikipedia article about the nitrogen cycle for more information.
What is the transfer of nitrogen from the atmosphere to plants and back to the atmosphere or directly into plants again?
The transfer of nitrogen from the atmosphere to plants and back occurs through a process called nitrogen fixation. This can happen through the action of nitrogen-fixing bacteria that convert nitrogen gas into a form that plants can use. Once plants assimilate this nitrogen, it can be returned to the atmosphere through processes like denitrification or can be transferred to other organisms through the food chain.
How do plants and animals get nitrogen is not from the atmosphere?
In rainforests where there is loads of leeching, plants get their nitrogen from other dead plants, where a nitrogen cycle is established
What molecule in the ground is nitrogen found when there is no oxygen around?
In the absence of oxygen, nitrogen in the ground is typically found in the form of nitrogen gas (N2). Nitrogen gas makes up about 78% of Earth's atmosphere and can dissolve in soil and groundwater, providing an essential nutrient for plants and microorganisms.
What plants absorb nitrogen from the atmosphere?
Cannabis
Where does nitrogen from the atmosphere go before it enters?
Nitrogen from the atmosphere primarily enters the soil through a process called nitrogen fixation, where certain bacteria convert atmospheric nitrogen (N₂) into ammonia (NH₃) or related compounds. This process occurs in the root nodules of specific plants, like legumes, or in the soil by free-living bacteria. Once in the soil, nitrogen can be taken up by plants or further transformed by other soil microorganisms through processes like nitrification and denitrification. Ultimately, nitrogen becomes part of the food chain as it is absorbed by plants, which are then consumed by animals.
When there is not enough nitrogen in the atmosphere for plants how do the plants get it?
Plants do not actually get their nitrogen from the atmosphere. They get it in compounds in the soil through their roots. Some plants form symbiotic relationships with bacteria in the soil. The bacteria draw nitrogen from the air and form nitrogen compounds. The plants can then use the nitrogen.
What part of the nitrogen cycle requires microorganisms or bacteria?
The nitrogen cycle heavily relies on microorganisms, particularly during processes like nitrogen fixation, nitrification, and denitrification. Nitrogen-fixing bacteria convert atmospheric nitrogen (N₂) into ammonia (NH₃), which plants can use. Nitrifying bacteria then convert ammonia into nitrites (NO₂⁻) and nitrates (NO₃⁻), essential nutrients for plant growth. Finally, denitrifying bacteria return nitrogen to the atmosphere by converting nitrates back into nitrogen gas, completing the cycle.
