The Carbon Cycle

Question 1

Carbon in the surface waters of the ocean includes:

Answer 1

dissolved gaseous carbon and carbon in bodies of organisms

Question 2

List all stocks of carbon from largest to smallest

Answer 2

Deep ocean, fossil carbon, reactive sediments, soil carbon, atmospheric carbon, plant biomass

Question 3

Flows of carbon

Answer 3

photosynthesis, respiration, decomposition, air-sea gas exchange, sedimentation

Question 4

Photosynthesis

Answer 4

algae, phytoplankton and plants convert atmospheric carbon dioxide into carbohydrates (simple sugars). By product of reaction is oxygen

Question 5

Photosynthesis equation

Answer 5

Carbon Dioxide + Water (—>energy from sun –>) Carbohydrates + Oxygen

Question 6

primary production

Answer 6

production of energy laden carbohydrates because these carbs form base of food chain

Question 7

Respiration

Answer 7

Process of organisms using carbohydrates for energy. produces carbon dioxide and water

Question 8

Respiration equation

Answer 8

carbohydrates + oxygen (–>metabolic enzymes–>) carbon dioxide + water + energy

Question 9

plant and animal material fossilized into rocks is

Answer 9

coal

Question 10

plant and animal material fossilized into liquid is

Answer 10

oil

Question 11

plant and animal material fossilized into gas is

Answer 11

natural gas

Question 12

energy cannot be created or destroyed, may only change forms. If the energy from the sunlight is used for photosynthesis, where does the energy go?

Answer 12

Energy is stored in the carbon bonds. created by photosynthesis and released through respiration.

Question 13

Combustion

Answer 13

process of burning fossil fuels

Question 14

where is the energy stored in fossil fuels?

Answer 14

In the carbon bonds

Question 15

combustion equation

Answer 15

Fossil fuels/plant biomass + oxygen (–>ignition–>) carbon dioxide + water +energy
