Nitrogen can combine and form nitrates primarily through two processes: biological nitrification and atmospheric nitrogen fixation. In biological nitrification, soil bacteria convert ammonia (NH3) into nitrites (NO2-) and then into nitrates (NO3-) through a series of oxidation reactions. In atmospheric nitrogen fixation, lightning or certain bacteria convert atmospheric nitrogen (N2) into ammonia, which can subsequently be oxidized into nitrates by soil microorganisms.

What are 4 elements that combine in many ways to form many molecules in organisms?
Carbon, hydrogen, oxygen, and nitrogen are the four key elements that combine in various ways to form molecules in organisms. These elements are crucial for the structure and function of biological molecules such as carbohydrates, lipids, proteins, and nucleic acids.
How do thunderstorms help in converting nitrogen to nitrates?
The short answer is yes. I am not sure about the amount but there are only two ways nature converts N2 into a form of nitrogen that is usable by plants. The two ways are microorganisms and lightning. I believe bacteria are the main nitrogen fixers, but there might also be some algae that convert nitrogen as well. We have also mastered fixing N2, the process is the Haber- Bosh process.
How does the nitrogen cycle work?
In the nitrogen cycle, nitrogen is converted between different chemical forms by different microorganisms. Nitrogen fixation by bacteria converts nitrogen gas into ammonia, which can be taken up by plants for growth. Nitrifying bacteria then convert ammonia into nitrites and nitrates, which are further processed by denitrifying bacteria back into nitrogen gas, completing the cycle.
How is nitrogen used by humans?
Ammonia, nitrates, nitrites
How can just a little more than 100 elements combine in different ways to form a huge variety of compounds?
The question itself contains the answer: they can combine in many different ways. Carbon is particularly good at this.
Hydrogen oxygen carbon and nitrogen what does this combination make?
These elements can combine in various ways to form different molecules and compounds. For example, hydrogen and oxygen combine to form water (H2O), carbon and oxygen combine to form carbon dioxide (CO2), nitrogen and oxygen combine to form nitrogen dioxide (NO2). The specific molecules formed depend on the ratios and arrangements of the elements.
3 Describe two ways in which nitrates can be replaced naturally in the soil?
1. lightning makes nitrates from nitrogen and oxygen in the air. the nitrates then get washed into the soil by rain. 2. animal and plants decompose- depositing organic nitrogen into the soil
What are two ways that nitrogen fixation can take place?
Lightning strikes and special bacteria that grow on plant roots.
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 is nitrogen changed into before being used by living things?
Nitrogen is changed into ammonia through a process called nitrogen fixation, typically carried out by soil bacteria or certain plants like legumes. Ammonia is then converted into other forms of nitrogen such as nitrites and nitrates that are taken up by plants for growth and utilized by other living organisms in the food chain.
What are 2 ways that nitrogen can be removed from the atmosphere?
Nitrogen can be removed from the atmosphere through the process of nitrogen fixation, where certain bacteria convert atmospheric nitrogen into forms that plants can use. Nitrogen can also be removed through lightning strikes, which can combine nitrogen molecules with oxygen to form nitrogen oxides that are washed out of the atmosphere by rain.

What is the molecular formula for nitrogen oxygen carbon and hydrogen?
Nitrogen, oxygen, carbon and hydrogen are elements that combine to form molecules in a vast number of ways. There is no single molecular formula for them. The symbols for these elements are: nitrogen: N oxygen: O carbon: C hydrogen: H
Which gas is produced during lightning?
The answer is (ii) Nitrogen dioxide. Nitrogen is available in air in bonded form N2. Lightning energy helps break this N2 bond and produces nitrogen ions. These ions combine with Oxygen to produce Nitrogen monoxide in the first step and then nitrogen dioxide. If there happens to be rain at the time of lightning, this NO2 dissolves in water to form nitric or nitrous acids and falls to earth. These acids are in usable form for many plants. This process is one of the ways for nitrogen fixation in the environment. Kalra
How are soil nitrates replaced?
Soil nitrates are replaced in various ways. One of the most common ways to replace soil nitrate is by suing synthetic fertilizers.
