A. forests
B.grasses
C.ocean
D.microbes
Homework Answers
Option C is correct.
Oceans are the largest carbon reservoir in carbon cycle. 71% of carbon is found dissolved in oceans. Carbon is recycled between atmosphere, ocean and through living and dead organisms. An image of carbon cycle is inserted below:-

Forests and soils contain roughly 2160 Gton of carbon in the form of wood, leaves, and humus. (The actual value is not known this accurately, but this choice makes the numbers work out well.) Suppose that all of the world’s forests were to burn down instantaneously and that all of the soil carbon was oxidized as well.By how much would atmospheric CO2 increase? By how much would O2 decrease? Express your answers in percentages. Assume that the burning equation is...

Q2. A heat pump cycle is operating reversibly between a warm reservoir at 20o C and a cold reservoir at -5o C. A second heat pump cycle is also operating reversibly between a hot reservoir at 30o C and a cold reservoir whose temperature, TC, is unknown. Given that the coefficient of performance of the first heat pump cycle is twice that of the second cycle, determine TC (in o C). Q3. You see a newspaper advertisement from an organization...
