Example Questions
Example Question #1 : Biochemical Cycles
Which of the following steps is not part of the carbon cycle?
Extraction
Transpiration
Combustion
Respiration
Photosynthesis
Transpiration
Transpiration concerns the process through which water is carried through plants from roots to small pores in leaves, where it evaporates into the atmosphere. Thus transpiration is not a part of the carbon cycle, which concerns the biochemical exchange of carbon.
Example Question #1 : Biochemical Cycles
All of the following are Carbon sinks in the Carbon Cycle except...?
The Ocean
The Atmosphere
Animals
Plants
The Atmosphere
The Atmosphere is largely the source of Carbon in the Carbon cycle. Plants utilize photosynthesis to convert atmospheric Carbon Dioxide into Glucose. Animals consume this Glucose and store it in their bodies until they die. the Ocean hosts a large amount of dissolved Carbon Dioxide gas and has Calcium Carbonate as a storage place in oceanic organisms like coral.
Example Question #1 : Biochemical Cycles
Which of these is a type of biogeochemical cycles?
Carbon cycle
Hydraulic cycle
All of these
Phosphorous cycle
Nitrogen cycle
All of these
All of these are biogeochemical cycles:
Carbon cycle - plants and animals consume carbon dioxide and release carbon dioxide during decomposition or respiration, then the carbon dioxide returns to the atmosphere.
Phosphorus cycle - similar to the carbon cycle, plants and animals consume phosphorous and release it during decomposition. Then the phosphorous returns to the ground and waterways by way of bacteria and processes such as mineralization.
Nitrogen cycle - this is the most complicated biogeochemical cycles. This is because it takes place in multiple situations, including: nitrogen fixation, nitrification, denitrification, and ammonification.
Hydraulic cycle - the water cycle. Water evaporates, wind moves air (and water), precipitation occurs.
