what is the largest carbon reservoir in the carbon cycle?
A. forests
B.grasses
C.ocean
D.microbes
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:-

Choose one: Which of the following is true of carbon cycling? Choose one: A. Growing forests act as carbon sources. B. The conversion of CO2 into biomass requires oxygen. C. Burning fossil fuels increases atmospheric carbon dioxide. D. The atmosphere is the largest carbon reservoir.
a)In the figure above, the circles indicate the reservoir size and the thin arrows indicate the carbon flux in Gt(C)/year. Which single reservoir holds the largest amount of carbon? [1 point] b) What is the combined carbon reservoir size of permafrost, soils, and vegetation? Answer should be a range. [1 point] c) What fraction is your answer to part b of your answer to part a; and what does this tell you? Answer should be a range. [2 points] d) Calculate...
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...
Consider a closed thermodynamic cycle that takes 201 kJ of heat from a hot reservoir at 449 °C, and rejects 131 kJ to a cold reservoir at 2 °C. What is O cycle in kJ/K?

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...
at temperature T and a lower- temperature reservoir at 280K. At steady state, the cycle develops 40k W of power while rejecting 1000kJ/min of energy by heat to the cold reservoir. (a) Sketch the representation of the power cycle (b) Determine T, in K. 7 marks
A Carnot engine extracts 910J from a 550K reservoir during each cycle and rejects 500J to a cooler reservoir. It operates at 22 cycles per second. Find the work done during each cycle. Find its efficiency. Find the temperature of the cool reservoir. Find its mechanical power output.

A reservoir contains 2.83 cubic meter of carbon monoxide at 6895 kPa and 23.6 deg C. An evacuated tank is filled from the reservoir to a pressure of 3497 kPa and a temperature of 12.4 deg C, while the pressure in the reservoir decreases to 6205 kPa and the temperature to 18.3 deg C. What is the volume of the tank?
