Carbon exists in Earth’s atmosphere primarily within molecules of ...

The Nucleus of all living cells.

What is the effect of animals not being able to use carbon dioxide, which leads them to exhale it into the atmosphere where plants can once again use it to make carbohydrates.

carbon cycles continually between theatmosphere (as carbon dioxide) and the biosphere (as carbohydrates).

carbon is in a linear progression between the atmosphere (as carbon dioxide) and the biosphere (as carbohydrates).

carbon cycles continually between the aquatics (as carbon dioxide) and the atmosphere (as carbohydrates).

carbon cycles continually between the deserts (as carbon dioxide) and the aquatics (as carbohydrates).

How do humans contribute to the carbon cycle?

By burning fossil fuels and other forms of biomass, such as wood.

By burning fossil fuels and other forms of biomass, such as lightning.

What is Nitrogen Fixation?

Many legumes(plants such as peas, soybeans, peanuts, and alfalfa) coexist with bacteria called Rhizobia. The bacteria live in the soil on the roots of the legumes. These bacteria are able to take nitrogen directly from the atmosphere and convert it into ammonia(NH 3).

Many legumes (plants such as peas, soybeans, peanuts, and alfalfa) coexist with bacteria called Rhizobia. The bacteria live in the soil on the roots of the legumes. These bacteria break down nitrogen compounds.

Many legumes(plants such as peas, soybeans, peanuts, and alfalfa) coexist with bacteria called Rhizobia. The bacteria live in the soil on the roots of the legumes. This adds nitrogen to the soil

What is denitrification?

Some bacteria in soil convert nitrates into nitrogen gas.

The process of converting nitrogen gas to nitrates.

The process of adding nitrogen to soil.

The process of breaking down organic matter

What is the result of the buildup of Nitrogen in the atmosphere due to excessive burning of Fossil Fuels?

Nitrogen compounds in the soil get carried away by rainwater.

What are some differences between the Carbon and Nitrogen Cylce?

Nitrogen processes of mineralization, nitrification, and denitrification.

The carbon cycle that primarily relate to photosynthesis , decomposition, and deposition .

Carbon travels from the ground to the biosphere. Nitrogen travels in atmosphere.
