A)
Photosynthesis is the process by which autotrophs (plants) convert light energy into chemical
energy. The formula for this is: 6CO + 6H O → C H O + 6O
Which part of this formula contains reactants and which part contains products?
(1 point)
2 2 6 12 6 2
6 12 6 2
The reactants are 6CO2 + 6H2O and the products are C6H12O6 + 6O2.
Cellular respiration is a series of chemical reactions that break down glucose to produce ATP.
The reactants for this reaction are C H O + 6O and the products are 6CO + 6H O.
Which of the following is the correct reaction for cellular respiration?
(1 point)
6 12 6 2 2 2
6CO2 + 6H2O → C6H12O6 + 6O2
C6H12O6 + 6O2 → 6CO2 + 6H2O
The correct reaction for cellular respiration is C6H12O6 + 6O2 → 6CO2 + 6H2O.
C) A reservoir is a place where something collects. The carbon cycle has four main reservoirs.
Which of the following are carbon cycle reservoirs? (MARK ALL THAT APPLY (2 points)
atmosphere
models
oceans
sediments (dirt)
terrestrial biosphere (ground)
The carbon cycle reservoirs are the atmosphere, oceans, sediments (dirt), and terrestrial biosphere (ground).
only four
Apologies for the confusion. The correct answer is:
The carbon cycle reservoirs are the atmosphere, oceans, sediments (dirt), and terrestrial biosphere (ground).
D) Models help to explain things that are difficult to understand or observe (see). A limitation of
models is that they cannot show all details of complex processes. What would be an
advantage to using a model? (1 point)
a model allows for a FULL view of all processes
a model allows for a visual of a process that is not visible to the naked eye
a model shows ALL details of complex processes
