What is the processes are in the correct sequence as to their occurrence in nature?
Photosynthesis, cellular respiration, nitrogen fixation, and decomposition occur in the correct sequence as they occur in nature. Photosynthesis converts sunlight into energy, cellular respiration converts food into energy, nitrogen fixation converts atmospheric nitrogen into a form plants can use, and decomposition breaks down organic matter into nutrients for plants.
What molecules are involved in the nitrogen cycle?
The nitrogen cycle involves several key molecules, including nitrogen gas (N₂), ammonia (NH₃), nitrites (NO₂⁻), nitrates (NO₃⁻), and organic nitrogen compounds. Nitrogen fixation converts atmospheric N₂ into ammonia, which can be further oxidized to nitrites and then nitrates through nitrification. Denitrification processes reduce nitrates back to nitrogen gas, completing the cycle. Additionally, organic matter decomposition releases organic nitrogen back into the soil, making it available for uptake by plants.
How is the nitrogen from a dead animal converted back to thr nitrogen?
When a dead animal decomposes, bacteria and fungi break down the organic matter, releasing nitrogen-containing compounds into the soil. Other bacteria then convert these nitrogen compounds back into atmospheric nitrogen through a process called denitrification. This atmospheric nitrogen can then be taken up by plants and reused in the ecosystem.
What is the step of the nitrogen cycle in order?
The nitrogen cycle consists of several key steps in order: nitrogen fixation, where atmospheric nitrogen (N₂) is converted into ammonia (NH₃) by bacteria or lightning; nitrification, where ammonia is oxidized into nitrites (NO₂⁻) and then into nitrates (NO₃⁻) by nitrifying bacteria; assimilation, where plants absorb nitrates and incorporate nitrogen into organic compounds; and denitrification, where denitrifying bacteria convert nitrates back into atmospheric nitrogen, completing the cycle.
Does the nitrogen cycle have no atmospheric component?
No, the nitrogen cycle has an atmospheric component. Nitrogen gas (N2) in the atmosphere is converted into compounds that can be used by living organisms through processes like nitrogen fixation and denitrification. This atmospheric nitrogen is essential for the functioning of the nitrogen cycle on Earth.
What is the cycle involving the exchange of nitrogen between organisms and the atmosphere?
The nitrogen cycle involves the process of nitrogen fixation by certain bacteria converting atmospheric nitrogen into forms usable by plants, which are then consumed by animals. Decomposers break down organic matter into ammonia and return nitrogen to the soil. Denitrification by bacteria converts nitrates back to atmospheric nitrogen to complete the cycle.
What is the processes are in the correct sequence as to their occurrence in nature?
Photosynthesis, cellular respiration, nitrogen fixation, and decomposition occur in the correct sequence as they occur in nature. Photosynthesis converts sunlight into energy, cellular respiration converts food into energy, nitrogen fixation converts atmospheric nitrogen into a form plants can use, and decomposition breaks down organic matter into nutrients for plants.
How do elements such as carbon and nitrogen get moved through the living world?
Carbon and nitrogen are cycled through the living world via processes such as photosynthesis, respiration, decomposition, and nitrogen fixation. Photosynthesis converts carbon dioxide into organic compounds, while nitrogen fixation converts atmospheric nitrogen into a form usable by plants. Respiration releases carbon dioxide back into the atmosphere, and decomposition breaks down organic matter, returning nutrients like nitrogen back into the soil.
What kind of organisms converts atmospheric nitrogen into a form that other organisms can use?
bacteria

What are The three ways that nitrogen is made available to plants?
Nitrogen fixation by bacteria in the soil or root nodules of leguminous plants converts atmospheric nitrogen into a form that plants can use. Decomposition of organic matter releases nitrogen back into the soil as ammonium. Application of nitrogen-containing fertilizers can supplement soil nitrogen levels for plant growth.
Where do these bacteria in the soil obtain their nitrogen?
Bacteria in the soil obtain nitrogen from various sources, such as organic matter, atmospheric nitrogen (N2), and nitrogen-fixing plants. Some bacteria can convert atmospheric nitrogen into a form that plants can use, while others break down organic matter to access nitrogen.
What do nitrates and organic matter produce?
Nitrogen gas becomes the ultimate product of nitrates and organic matter and complete the nitrogen cycle. Organic matter converts into ammonium, which oxidizes into ammonia and then into nitrites. Nitrites oxidize into nitrates, which reduce into nitrogen gas.
How does nitrogen fixation work in the process of converting atmospheric nitrogen into a form that plants can use for growth?
Nitrogen fixation is the process of converting atmospheric nitrogen into a form that plants can use for growth. This is done by certain bacteria, like Rhizobium, that live in the roots of leguminous plants. These bacteria have the enzyme nitrogenase, which converts atmospheric nitrogen into ammonia, a form of nitrogen that plants can absorb and use for their growth.
What are four forms of nitrogen found in the biosphere and where are they found?
The four forms of nitrogen found in the biosphere are: atmospheric nitrogen (N2), organic nitrogen (as part of biomolecules like proteins), ammonium (NH4+), and nitrate (NO3-). Atmospheric nitrogen is found in the air, organic nitrogen is found in living organisms and decaying matter, while ammonium and nitrate are found in soil and water.
What is the need of fixing atmospheric nitrogen find out the various ways by which atmospheric nitrogen is fixed?
Why does atmospheric nitrogen need to be converted?
Which event breaks down the nitrogen in the atmosphere and converts it to a form that can be used by plants and animals?
Nitrogen fixation is how atmospheric nitrogen is processed. This occurs during lightning strikes but mainly is processed by diazotrophs, or free living bacteria with nitrogenase.
