This is the change of solid water (ice) into liquid state.
What is melting?
100
Organic molecules, and all living organisms, are made of this element.
What is carbon?
100
78% of Earth's atmosphere is made of this.
What is nitrogen?
100
Fermentation provides energy without using this element.
What is oxygen?
100
Name each of the three energy-producing cellular processes we've studied this year.
What is photosynthesis, cellular respiration, and fermentation.
200
This is the conversion of liquid water to a gaseous state, allowing water vapor to enter the atmosphere.
What is evaporation?
200
If you were to make a physical model of the carbon cycle, what shape would the model take on?
What is a circle?
200
These organisms must obtain nitrogen from the food they eat.
What are consumers?
200
Under what conditions is lactic-acid fermentation most likely to occur?
What is intense exercise?
200
Which cellular processes occur in plants?
What is photosynthesis AND cellular respiration?
300
In which process do molecules of liquid water absorb energy and change into the gas state?
Evaporation
300
What is the human impact on the carbon cycle?
More carbon is released into the atmosphere than under natural conditions.
300
True or False: Humans absorb nitrogen from air when they breathe.
False
300
This is a benefit of fermentation.
What is extra energy (without need for oxygen)?
300
How are photosynthesis and cellular respiration related?
Opposite reactions
400
This must occur just before precipitation.
What is condensation?
400
These three niches all rely upon and participate in the carbon cycle.
What is producers, consumers, and decomposers?
400
Which cellular compound contains nitrogen?
What is DNA?
400
How is fermentation similar to cellular respiration?
Provides energy to an organism
400
What are the products of photosynthesis?
What is oxygen and glucose?
500
What is the biological importance of the water cycle?
All organisms must have water to survive, and therefore water must continuously move in a cycle to get to those organisms. Must occur in order to support and maintain living ecosystems.
500
This is the basic chemical formula for glucose.
What is C6H12O6?
500
Which nutrient contains significant amounts of nitrogen?
What is protein?
500
Fermentation produces this material, which causes muscle soreness.
