What are 4 elements that combine in many ways to form many molecules in organisms?
Carbon, Hydrogen, Oxygen, and Nitrogen are the four base elements of life.
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?

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.
What is the Nitrogen cycle?
Water pollution affects the nitrogen cycle the least. The nitrogen cycle is the cycle of nitrogen as it enters earth, becomes fixed, and leaves earth, back to the atmosphere. The only way that water pollution can affect the nitrogen cycle is if there is too much trash in one area of a body of water, thus clogging the surface and not allowing algae to absorb the nitrogen. It could also clog the surface and not allow denitrifying bacteria in waterlogged soil to release the nitrogen back into the atmosphere.
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 is nitrogen changed into before being used by living things?
lightning & bacterial action (nitrogen fixers).
What are two ways that nitrogen fixation can take place?
Lightning strikes and special bacteria that grow on plant roots.

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

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.
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

In what ways do farmers contribute nitrates to the soil?
by using fertilizer
Why are there more materials than elements?
Because the elements can combine in many ways to form compounds, and compounds can be mixed in many differed ways. Moreover, some elements occur in different forms. The elements carbon and hydrogen alone combine for form thousands of compounds.
