1
Q
Carbon in the surface waters of the ocean includes:
A
dissolved gaseous carbon and carbon in bodies of organisms
2
Q
List all stocks of carbon from largest to smallest
A
Deep ocean, fossil carbon, reactive sediments, soil carbon, atmospheric carbon, plant biomass
3
Q
Flows of carbon
A
photosynthesis, respiration, decomposition, air-sea gas exchange, sedimentation
4
Q
Photosynthesis
A
algae, phytoplankton and plants convert atmospheric carbon dioxide into carbohydrates (simple sugars). By product of reaction is oxygen
5
Q
Photosynthesis equation
A
Carbon Dioxide + Water (--->energy from sun -->) Carbohydrates + Oxygen
6
Q
primary production
A
production of energy laden carbohydrates because these carbs form base of food chain
7
Q
Respiration
A
Process of organisms using carbohydrates for energy. produces carbon dioxide and water
8
Q
Respiration equation
A
carbohydrates + oxygen (-->metabolic enzymes-->) carbon dioxide + water + energy
9
Q
plant and animal material fossilized into rocks is
A
coal
10
Q
plant and animal material fossilized into liquid is
A
oil
11
Q
plant and animal material fossilized into gas is
A
natural gas
12
Q
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?
A
Energy is stored in the carbon bonds. created by photosynthesis and released through respiration.
13
Q
Combustion
A
process of burning fossil fuels
14
Q
where is the energy stored in fossil fuels?
A
In the carbon bonds
15
Q
combustion equation
A
Fossil fuels/plant biomass + oxygen (-->ignition-->) carbon dioxide + water +energy
