The Carbon Cycle
Plants use this to make sugar and oxygen.
What is photosynthesis?
Deposits burned as fossil fuels.
What phosphorus is mostly contained in.
What are minerals and rocks?
The percent of nitrogen in our atmospher.
What is 78%?
Animals use this process to make CO2.
What is respiration?
Causes more CO2 to be released in the atmosphere?
What is the burning of fossil fuels?
An essential nutrient for life that makes up important chemicals.
What is phosphorus?
A special bacteria that can use nitrogen in our atmosphere for benefits of organisms.
What is nitrogen-fixing bacteria.
The products of photosynthesis?
What is sugar and oxygen?
Another natural source for CO2.
What are volcanoes?
What phosphorus in solid can be washed away into.
What are water basins?
High organism use nitrogen to make this.
What are proteins?
The products of repiration.
What is CO2?
Cause of the greenhouse effect.
What is too much CO2 in the atmosphere?
Another source of phosphorus in water.
What is man made pollution?
Animals eat this which is returned to the soil by animal waste.
What are plants containing nitrogen?
The main regulator of CO2 in the atmosphere.
What is the ocean?
The equation for photosynthesis.
What is H2O+CO2+energy=C6H12O6+O2?
Too much phosphorus in water can lead to this.
What is plant overgrowth?
Animal decay by the action of bacteria creates this.
What is nitrate and ammonia?
