CO2
What is the molecular formula for carbon dioxide?
100
CO2
What is released as a waste product of cellular respiration
100
evaporation
How does water enter into the atmosphere?
100
nitrogen fixation
What is the name of the process in which nitrogen gas from the atmosphere is converted into a soluble form in the soil (ammonium)?
100
Both are involved in the carbon cycle. Photosynthesis allows autotrophs to take in carbon dioxide to produce glucose. Cellular respiration breaks down the glucose to produce ATP and carbon dioxide is released into the atmosphere as a waste product. Their equations are also opposite.
Explain the connection between photosynthesis and cellular respiration.

C6H12O6
What is the molecular formula for glucose?
200
photosynthesis
What is the name of the process in which carbon dioxide is taken from the atmosphere?
200
precipitation
When water condenses, _____________ is formed.
200
nitrogen fixing bacteria
What types of organisms can fix nitrogen?
200
Some plants, like corn and rice, are nitrogen lovers and extract the majority of the nitrogen from the soil. Farmers will then plant a legume such as soybeans or cowpeas to replace the lost nitrogen.
Why do farmers rotate their crops?
300
reactants
What are the molecules that combine during a chemical reaction called? They are found first, on the left side of a chemical equation.
300
plants and other autotrophs
What types of organisms are able to remove carbon dioxide from the environment?
300
runoff
Storm water that picks up pollutants and then flows into a body of water is called __________.
300
nitrification
What is the name of the process in which ammonium is converted to nitrate, a form of nitrogen that plants can use?
300
They release huge amounts of carbon dioxide into the atmosphere when they are burned.
How are fossil fuels contributing to the carbon cycle?
400
products
What do you call the molecules that are formed during a chemical reaction? They are found on the right side of the chemical equation.
400
eating
How do consumers take in their carbon compounds?
400
water vapor
What is the gaseous form of water called?
400
denitrification
What is the name of the process in which bacteria convert nitrate back into nitrogen gas which is then released back into the atomosphere?
400
deforestation, irrigation, urban sprawl, damming rivers
How are humans affecting the water cycle?
500
a balanced equation
What do you call a chemical reaction whose atoms are equal on both the reactant and product side of the equation?
500
They are opposites, the products in photosynthesis are the reactants in cellular respiration and vice versa.
How are the overall chemical equations for photosynthesis and cellular respiration similar?
500
Heat from the sun (solar energy) causes water to evaporate
What is the energy source that drives the water cycle?
500
legumes- peas beans and clover
What types of plants contain root nodules with nitrogen fixing bacteria in them?
500
nitrogen fixing bacteria, lightening, humans taking it to make fertilizer
What are the three ways in which atmospheric nitrogen can be fixed into soluble compounds that plants can take in?
