Question
. Carbon Cycle:
*Carbon fixation occurs during ____________________ when sugars get built out of carbon dioxide.
*Carbon dioxide is released from organic carbon molecules by two main
processes: ______________ and __________.
[Note: one of these processes is a biological process and one of these processes is a physical process.]
* Name one large reservoir of inorganic carbon.
[There is more than one right answer here.]
*Explain one of man’s major impacts on the carbon cycle. [6 pts]
16. *List three different causes of the reduction in US wolf populations seen in the late 1800’s and early 1900’s. (Don’t use “man” as a cause. If you do, you won’t have enough answers. State what man has done instead.)
*List 3 different impacts that the loss of wolves had on Yellowstone National Park.
*How long has it been since the reintroduction of wolves to the park occurred?
*Have there been significant effects on the ecosystem due to the reintroduction?
Explanation / Answer
Carbon fixation occurs during photosynthesis where sugars are formed from carbon dioxide.
CO2 is released during respiration and decomposition.
Large reservoir of inorganic carbon is atmosphere where it is found in the form of CO2.
The man's major impact on carbon cycle is combustion of fossil fuels
