Explain the role of microorganisms in Earth's nitrogen cycle.
convert nitrogen gas from the environment into solid nitrogen molecules that plants can utilize in the soil
100
The oxygen cycle allows for regeneration of what gas in the atmosphere ?
Diatomic Oxygen (O2)
100
What is breathe ?
Pants and animals use the oxugen cycle to do this .
200
The two forms of oxygen formed in the atmosphere are ozone and oxygen.
In the oxygen cycle, the movement of oxygen takes place within
200
Life on earth would not be possible without ?
Carbon
200
What is the nitrogen cycle ?
The cycling of nitrogen through the ecosystem
200
What is The Oxygen Cycle demonstrates how what is made ?
Oxygen

What is the oxygen cycle
Helps both plants & animals obtain food
300
The oxygen cycle is an example of the biogeochemical cycle.
The oxygen cycle is the movement of oxygen from the atmosphere through a series of intricate processes. It helps maintain the oxygen level of the atmosphere
300
Give examples of carbon forms found on Earth
amorphous, graphite, and diamond
300
Why is the nitrogen cycle vital for plants
Plants need nitrogen to synthesize chlorophyll
300
What percentage of the atmosphere is oxygen ?
21%
300
What is cells breaking down oxygen ?
Gives us energy

Explain the significance of the oxygen cycle in supporting life on earth.
To maintain the concentration and level of Oxygen in the atmosphere.
400
What is the name of the forms of carbon ?
Allotropes

Explain the significance of the nitrogen cycle to life on Earth
nitrogen is an essential nutrient for sustaining life on Earth
400
What are the regions that movement of oxygen occurs
Atmosphere and Biosphere

describe the earths oxygen cycle
oxygen cycle begins with the process of photosynthesis in the presence of sunlight, releases oxygen back into the atmosphere, which humans and animals breathe in oxygen and breathe out carbon dioxide, and again linking back to the plants.
500
Describe the different forms taken by carbon and the reservoirs where they are found.
Carbon is stored on our planet in the following major sinks (1) as organic molecules in living and dead organisms found in the biosphere; (2) as the gas carbon dioxide in the atmosphere; (3) as organic matter in soils; (4) in the lithosphere as fossil fuels and sedimentary rock deposits such as limestone, dolomite

Describe and illustrate Earth's nitrogen cycle
Nitrogen Cycle is a biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere

What happens when oxygen meets metal ?
Oxidation
