100
What is the order of events?
What is evaporation, condensation, and precipitation.
100
What is the nitrogen cycle?
What is process ‘free’ nitrogen in the air to a compound for organisms to use.
100
What happens in the oxygen cycle?
What is producers undergo photosynthesis to produce energy and food for themselves. Animals carry out respiration. Combustion. Decomposition.
100
What breaks down organisms and releases carbon dioxide?
What is decomposers.
100
What cycle is this?
What is the water cycle.
200
What form(s) is water in the water cycle. (solid, liquid, or gas)
What is solid, liquid, and gas.
200
What type of nitrogen can organisms consume?
What is fixed nitrogen.
200
What happens to the oxygen when humans cut down trees and burn fuel?
What is, it decreases.
200
What is the source of carbon found in living matter?
What is carbon dioxide.
200
What powers evaporation?
What is the sun's heat.
300
What percent of the Earth is water?
What is 70%.
300
What single celled organisms play a role in nitrogen fixation? Where do they live?
What is bacteria, they live on nodules on the roots of legumes.
300
Explain what Photosynthesis is.
What is, photosynthesis is the process where plants make sugars and oxygen using carbon dioxide and sunlight.
300
What type of organisms use photosynthesis for carbon dioxide fixation?
What are producers.
400
Why is the water cycle important?
What is because it circulates water into and out of the atmosphere and gives organisms the water to live.
400
What makes nitrogen ‘free’?
What is it not combined with other types of atoms.
400
Explain what respiration is.
What is, respiration is where animals take in oxygen,glucose and convert it to carbon dioxide,heat energy and water.
400
What happens in the carbon cycle?
What is the circulation of carbon dioxide in different forms.
400
What 2 cycles is respiration linked between?
What is oxygen and carbon cycle.
500
Describe the 4 main stages in the water cycle.
What is precipitation, the heavy droplets of rainfall. Evaporation, the process in which molecules of liquid water absorb energy and change to a gas. Condensation, the process in which the water vapor combine and become a cloud. Runoff, the time in which water runs off into a river, ocean, or stream, to begin evaporation again.
500
What percentage of the air is nitrogen? Is it free or fixed?
What is 78%, it is free.
500
Why is the oxygen cycle important?
What is, it is important because we need the cycle to live and thrive including the plants. This cycle is necessary for human and plant life.
500
Carbon dioxide is added directly to the atmosphere as a byproduct of what?
What is respiration.
