Carbon Cycle
Plants using CO2 to make sugar and oxygen.
What is photosynthesis?
Not found in the free state in nature, contained mostly in ricks and minerals.
What is phosphorous?
78% nitrogen gas.
What is the atmosphere?
Continuous movement of water in earths atmosphere
What is the water cycle
Animals using oxygen to make CO2.
What is respiration?
Moves between soil and plants, which are eaten by animals. Animals use it, then their waste products.
What is the phosphorus cycle?
Cannot directly use all nitrogen found in our atmosphere.
What are animals and plants?
Conversion of water vapor to glass liquid
what is condensation
The main regulator of CO2 in the atmosphere because CO2 dissolves easily in it.
What is the ocean?
Some of the phosphorus in soils can be washed away into them.
What are basins?
Can directly use nitrogen in our atmosphere and “fix” it so other organisms can benefit.
What are nitrogen-fixing bacteria?
any liquid or frozen water that forms in the atmosphere and falls back to the earth
What is precipitation?
Causes more CO2 to be released in the atmosphere today than in the past.
What is burning of fossil fuels?
Another source of phosphorus in water.
What is man made pollution?
Products rich in nitrogen, useful for plants to use again.
What is ammonia and nitrate?
Evaporation of water through plant leaves
What is transpiration?
Another natural source for CO2.
What are volcanoe?
Too much phosphorus in water leads to this, strangling all other life forms in the water.
What is plant overgrowth?
Bacteria in the soil that can break down ammonia into the gaseous form of nitrate.
What is denitrification?
Process of turning liquid to vapor
What is evaporation?
