Carbon Cycle
Three examples of these are coal, oil, and natural gas.
What are fossil fuels?
Phosphorus is mostly contained in these 2 things.
What are rocks and minerals?
78% of our atmosphere.
What is nitrogen gas?
How groundwater is released to the atmosphere.
What is through transpiration?
The process animals use to make CO2.
What is respiration?
Can cause plant overgrowth, strangling other living things in the water.
What is too much phosphorus in the water?
Special bacteria that can directly use nitrogen in our atmosphere and “fix” it so other organisms can benefit.
What is nitrogen-fixing bacteria?
When water falls to the surface.
What is percipitation?
Where CO2 easily dissolves.
What is the ocean?
Where excess fertilizer washes into.
What are rivers, streams, and oceans?
How bacteria release nitrogen gas.
What is through denitrification?
What happens after water from oceans and lakes evaporates.
What is condenses to form clouds?
Too much CO2 in the air can be responsible for this effect.
What is the greenhouse effect?
A source of phosphorus in water.
What is man-made pollution?
Use nitrogen to make their protein.
What are higher organisms?
When water seeps into the ground.
What is becomes groundwater?
What are sugar and oxygen?
This helps return the sulfur for the next generation of phosphorus in the soil.
What are animal waste products?
How nitrogen is released by animals.
What is through excretion and decomposing matter?
Where surface runoff water goes to.
What are rivers to lakes and oceans?
