What is the Earth's Oxygen Cycle's purpose?
Helps move oxygen through the three main regions of the Earth.
100
What is the Carbon Cycle?
The process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere.

What are four important processes in the Nitrogen Cycle?
Fixation, ammonification, nitrification, and denitrification.

Earth's Oxygen Cycle helps move oxygen through what three main regions of the earth?
Atmosphere, Biosphere, and Lithosphere
200
What are the four processes of the Carbon Cycle?
Photosynthesis, Decomposition, Respiration and Combustion.
200
How long does the Nitrogen Cycle take to complete one whole cycle?
About 2-6 weeks.
300
What are the two major components of the Oxygen Cycle?
Photosynthesis and respiration.

What is the Carbon Cycle Process in order?
Carbon dioxide is absorbed by producers to make glucose in photosynthesis. Animals feed on the plant passing the carbon compounds along the food chain. Most of the carbon they consume is exhaled as carbon dioxide that was formed during aerobic respiration.
