This worksheet answers questions pertaining to the carbon and nitrogen cycles in water. You will need to understand how each element affects the other. Essentially, carbon is a basic atom and has two functions in the atmosphere: to hold atmospheric gases and to create energy. The carbon cycle starts in the atmosphere with nitrogen gas and moves through different reservoirs. It is then taken back out of the atmosphere through decomposition and storage in the soil and forests. The human body uses carbon from food to make energy, and then releases it back into the atmosphere in the form of the nitrogen gas we breathe.

Eventually, this carbon returns to the atmosphere as ammonia. This is an important process for maintaining a balanced ecosystem. The oxidation of carbon dioxide in the atmosphere will eventually cause the resulting gases to cycle back to the atmosphere. This is the short-term cycling of carbon. The long-term cycling of nitrogen occurs over millions of years. When this happens, the resulting nitrogen is used in the production of fertilizer.
The water carbon and nitrogen cycle is the most important cycle in the world. When nitrogen is absorbed by plants, it is converted into a more usable form. While some nitrogen can be fixed by blue-green algae and lightning, the majority is modified by bacteria in soil. The bacteria combine the nitrogen with oxygen and hydrogen to produce nitrates, ammonia, and other compounds that are useful for life.

As a result of this short-term cycling, nitrogen is a very useful element in the environment. Because of this, it has to be changed into a useful form. Some of the carbon can be fixed by lightning, but most of it is modified by bacteria in the soil. They transform nitrogen into ammonia and nitrates. This process is the most important factor in the cycle.
Since nitrogen is the most abundant gas in the atmosphere, it must be converted into a more usable form in order to be useful. Some of it is fixed by blue-green algae and lightning, but much of it is modified by bacteria in soil. In this way, carbon is transformed into oxygen, hydrogen, and nitrates. This is known as nitrification. Those substances are used to make soils and produce a variety of products, including a variety of chemicals.

When an organism dies, it stores carbon as chemical energy. This carbon is released into the environment when the organism decomposes. In addition, when the organism decomposes, it turns into fossil fuels like oil and natural gas. This storage process continues for millions of years. However, some animals may become fossil fuels. As a result, they can cause other types of pollution.
The carbon stored in an organism is released into the environment after the organism dies. The carbon is buried when the organism dies and subsequently is transformed into fossil fuels, including oil and coal. As a result, the carbon stored in an organism is trapped for millions of years, making them useful in the modern world. So, the carbon stored in a fossil fuel is also a source of CO2.

The carbon that is stored in a living organism is released into the environment when the organism dies. In a fossil fuel, the carbon can stay inside an organism’s cells until it dies. In contrast, the carbon that is stored in an organism’s tissue is released into the environment when the organism is burned. This process is called combustion, and it releases carbon into the atmosphere. The two cycles work together in the same way.
One of the most important sources of atmospheric CO2 is deforestation. Trees are a source of CO2 when they are alive, but when they are burned they become carbon sources. In this way, forests go from carbon sink to carbon source. In Mexico, forests are being burned to make way for agriculture. Other long-term sources of carbon are fossil fuels, such as coal and oil. The latter two are long-term sinks because they are converted into carbon sources.
