In natural circumstances, accumulated reserves of carbon such as peat, coal and oil represent a sink or natural diversion from the cycle. Eventually, the carbon in these sinks returns to the cycle through the action of geological processed which return deposits to the surface for oxidation. (a) What is the effect of human activity on the amount of carbon stored in sinks? (b) Describe two global effects resulting from this activity: (c) What could be done to prevent or alleviate these effects?

Write each English sentence as an equation in two variables. Then graph the equation. The y-value is four more than twice the x -value.

What are two main natural carbon sinks?

What type of carbon sink does the author propose people use?

Use the alternative form of the derivative to find the derivative at x=c (if it exists).f(x) = 3/x, c=4

Describe the biological origin of the following geological deposits: (a) Coal: (b) Oil: (c) Limestone: (d) Peat:

Use the fundamental identities to simplify the expression. Use the table feature of a graphing utility to check your result numerically. $\cos x\left(1+\tan ^{2} x\right)$

What is the role of methanogenic archaea in the carbon cycle?

Consider the following game: A player throws a fair die repeatedly until he rolls a 2, 3, 4, 5, or 6. In other words, the player continues to throw the die as long as he rolls 1s. When he rolls a “non-1,” he stops. What is the expected number of rolls needed to obtain the first non-1?

What would be the effect on carbon cycling if there were no decomposers present in an ecosystem?

Describe the biological origin of the following geological deposits:
(a) Coal
(b) Oil
(c) Limestone
