Which of the following would produce/release carbon into the carbon cycle
plants releasing it after photosynthesis
plants storing it as part of glucose
burning trees
rocks forming with carbon in their chemical makeup
Which of the following would absorb carbon?
The ocean, which leads to ocean acidification
Animals, through cellular respiration
Combustion, from using fossil fuel
Volcanic eruptions, pulling carbon into the lava
How do decomposers affect the carbon cycle?
Decomposers use carbon dioxide as part of breaking down decaying matter
Decomposers release carbon in organic matter and release it through their own respiration
Decomposers aid in photosynthesis with their chloroplasts
Decomposers have no impact on the carbon cycle
Which of the following are the primary driving force for the nitrogen cycle?
The sun
bacteria
animals
plants
Which cycle is driven by the sun?
nitrogen cycle
water cycle
carbon cycle
phosphorus cycle
What is it called when nitrogen from the atmosphere gets captured by bacteria?
nitrogen fixation
ammonification
combustion
condensation
After water evaporates from the ground, what would happen next that would cause clouds to form?
precipitation
condensation
infiltration
percolation
Which cycle(s) involves changes in the chemical form of the matter?
water
nitrogen

nitrogen
carbon
none of the above
Plants and animals can use nitrogen without the presence of bacteria
true
false
Which of the following is NOT a step in the carbon cycle?
plants releasing carbon dioxide during photosynthesis
animals releasing carbon dioxide during cellular respiration
weathering causing the carbon in rocks to be released as carbonic acid
carbon being released from trees as a forest fire occurs
What is it called when water goes under ground, into aquifers?
infiltration
