Carbon Cycle Flashcards

Terms Definitions
CO2
presense of oxygen
fermentation
cellular respiration without oxygen done by bacteria and resulting in production of ethanol
Where is most carbon found?
In compounds.
photosynthesis
reaction done by producers using energy from light to make glucose sugar and oxygen from water and carbon dioxide
Biochemical
the exchange of elements and simple substances between the living system and the environment
How long could a tree hold it's carbon?
Centuries.
Greenhouse effect
Some of the infrared radiation passes through the atmosphere but most is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds. Warms earth's surface and lower atmopsphere
How long could a flower hold it's carbon?
A year.
How long does carbon stay in the hydrosphere?
100,000 years.
global warming
an increase in the temperature of the atmosphere due to accumulation of carbon dioxide in the atmosphere
What is the carbon cycle "tied" to?
The process of photosynthesis.
CO2, Methane, Nitrous oxide
greenhouse gases in order of least potent
Where are significant amounts of carbon found?
Fossil fuels such as, coal, natural gas, and petroleum.
What will eventually happen to the sedimentary rock that has developed on ocean floor?
The rocks will be expose on earth's surface, by time and plate tectonics.
What are two ways that carbon gets back into the atmosphere?
The breathing of animals, the decay of dead plants and animals releases the carbon that was used within the organisms' living cells, the burning of biofuels either by man or nature (forest fire), volcanic eruptions, and weathering of rocks.
methane
absense of oxygen
plankton
speeds up absorption of CO2
oceans
absorbs atmospheric CO2 (slow process)
ATP
adenosine triphospate, the molecule cells use directly for an energy source
Biochemical cycles
Water, Carbon, Nitrogen, Phosphorus, Sulfer
anaerobic respiration
cellular respiration without oxygen resulting in fewer ATP and lactic acid
combustion
burning of an organic molecule which releases carbon dioxide into the atmosphere
Where is the largest carbon reservoir on earth?
The ocean.
cellular respiration
conversion of energy from bonds of glucose to ATP
What forms from the calcium carbonate containing organisms when they die and settle on the ocean floor?
Sedimentary rock, limestone.
Where is carbon found in the ocean?
The ocean floor.
What are some examples of ocean organisms that contain calcium carbonate?
Some shellfish, and coral.
What spheres does carbon move through?
Atmosphere, biosphere, geosphere, and hydrosphere.
What are the common compounds that contain carbon?
Carbon dioxide and calcium carbonate.
How does carbon exist in the atmosphere?
In the form of carbon dioxide.
How is the oxygen cycle related to the carbon cycle?
Plants release oxygen which animals breathe in then they breathe out carbon dioxide that the plants use to make more oxygen.
