What is a definition for orbit and atmosphere?
Definition for : ORBIT : A fixed path on which a planet moves around a star. ATMOSPHERE : A layer of air (composed of different gases e.g. oxygen, nitrogen etc. ) surrounding the Earth.
What is the diffrence between fixed nitrogen and free nitrogen?
OK well free nitrogen is fixed by bacteria that live in the soil. some bacteria live in nodules, or bumps , on certain plant roots. the bacteria get food from the plants, and plants absorb fixed nitrogen from the bacteria. animals get nitrogen by eating plants or by eating prey that have eaten plants. fixed nitrogen may enter the soil in other ways too. a small amount of free nitrogen in the air by lighting. it is carried to the ground by rainfall. fixed nitrogen also enters the soil because of decomposers. decomposers break down dead organisms, and fixed nitrogen is released in the soil. the fixed nitrogen can be absorbed by plant roots.
What are two forms of fixed nitrogen?
Two forms of fixed nitrogen are ammonia (NH3) and nitrate (NO3-). Fixed nitrogen refers to nitrogen that has been converted from its inert atmospheric form (N2) into compounds that can be used by plants and other organisms.
What is the difference between free nitrogen and fixed nitrogen?
Free nitrogen refers to the nitrogen gas (N2) present in the atmosphere, which is not readily available for use by most organisms. Fixed nitrogen, however, is nitrogen that has been converted into a form that can be utilized by plants and other organisms, such as ammonia, nitrate, or nitrite. This conversion process is often carried out by nitrogen-fixing bacteria in the soil.
What is the difference between fixed nitrogen and free nitrogen?
Fixed nitrogen refers to nitrogen that has been converted into a form that can be readily used by plants, such as ammonia or nitrates. Free nitrogen, on the other hand, refers to nitrogen gas (N2) that makes up about 78% of the Earth's atmosphere and is not readily available for use by most organisms until it is fixed.
What percentage of nitrogen is fixed by nitrogen fixing bacteria?
Around 70-80% of nitrogen in the atmosphere is fixed by nitrogen fixing bacteria through a process called nitrogen fixation. This converted nitrogen is then made available for use by plants and other organisms in the environment.
What are 3 ways that nitrogen can be fixed?
Nitrogen can be fixed through biological nitrogen fixation by nitrogen-fixing bacteria, through industrial processes like the Haber-Bosch process, and through lightning in the atmosphere which converts nitrogen gas into nitrogen compounds that can be used by plants.
What are the two ways nitrogen can be fixed?
Nitrogen can be fixed by lightning during thunderstorms, a process that converts nitrogen gas (N2) into nitrates (NO3-) that can be used by plants. Nitrogen can also be fixed by certain soil bacteria called nitrogen-fixing bacteria, which convert N2 into a form that can be taken up by plants.
What are two major ways in which nitrogen is fixed in ecosystems?
Nitrogen can be fixed in ecosystems through biological processes, like by nitrogen-fixing bacteria that convert atmospheric nitrogen into a usable form for plants. It can also be fixed through human activities, such as the use of nitrogen fertilizers in agriculture.
What are the bacterias in the nitrogen cycle?
Nitrogen needs to be fixed before it is used by plants.
