The Calvin cycle splitting water in the dark RX's.
The water splitting during the light RX's.

FALSE
TRUE
Carbon travels from the atmosphere as carbon dioxide gas to plants and then to animals. When carbon changes form from a gas in the atmosphere to the tissues in a plant as EX: glucose" it is said to be_____.
dark RX
fixed
inputs
decomposed
(a) (b) (c)
Match the form of carbon forms by clicking on one and clicking on its match.
carbon dioxide
(gas in atmosphere)
glucose
(solid in plant tissue)
cellulose
(solid in plant cell walls)
Select the best explanation of what is happening in the graph.
the rate of reaction decreases with increasing CO2 concentration
the rate of reaction increases then levels off with increasing CO2 concentration
the rate of reaction decreases with descreasing CO2 concentration
the rate of reaction increases with increasing CO2 concentration
Using the Earth Gif as a hint...Propose an explanation as to why gaseous carbon dioxide levels oscillate (go up then down) seasonally in the northern hemisphere.
Northern hemisphere=more ocean=less photosynthesis in summer and more photosynthesis in winter; therefore causing CO2 levels to go up in summer and up in winter.
Northern hemisphere=more land mass=more photosynthesis in summer and less photosynthesis in winter; therefore causing CO2 levels to go down in summer and up in winter.
