biogeochemical cycle
Carbon cycle is the
Photosynthesis, reactants, chlorophyll, green
Carbon dioxide in the atmosphere gets captured by plants to be used in a chemical process called _____. In this process carbon dioxide is used as one of the ______ along with water. The plant converts these reactants into sugars that it stores within its own body. The carbon is now stored within the producer. The pigment called _____ is used to make photosynthesis happen and it is _____in the color
Greenhouse, traps
Carbon dioxide is called a ____ gas because it warms our atmosphere. It does this by absorbing the heat from the sun and preventing it from escaping outside of our atmosphere. This _____ heat in our atmosphere and causes warning
Assimilation, detritus
Carbon moves through the food chain in a process called_____when one organism takes in the carbon containing nutrients from another into it's own body. This way, carbon is found in all living organisms as well as the _____they produce as their waste and dead remains.
Deposition
Process in which sediment is laid down in new locations.
asssimilation
This is the process of moving carbon through food chain
Death and decomposition
This process converts the carbon in living organisms into detritus and the detritus into nutrients that go into the soil
Fossilization
This process creates fossil fuels
assimilation
This process describes an element moving through the different living components and detritus of a food web
assimilation
This process helps create the bodies of producers
Fossilization
This process involves heat, pressure, and a lot of time
deforestation
This process involves the removal of trees from a large area. This results in less producers for photosynthesis therefore it decreases the amount of CO2 that is removed from the atmosphere
Combustion
This process occurs when a fuel source (e.g. fossil fuels or trees) are burned. This releases carbon dioxide into the air
Fossilization
This process occurs when dead organisms get buried over a long time, and exposed to increase pressure and heat to convert them to fossil fuels
Cellular respiration
This process uses glucose and oxygen and converts it into water and carbon dioxide and energy. It adds CO2 to the atmosphere
Cellular respiration
This products of this reaction are CO2 and H2O
Death, decomposition, detritus, heat, fossilization, oil/petroleum, coal, natural gas, peat, Saudi Arabia
Through the process of____and____producers and consumer get converted into____by decomposers. This waste now contains carbon that can be compressed over a long period of time, with a lot of pressure and____to create fossil fuels in a process called_____. Four examples are ____, which is used the most globally, then____, which is used the second most, then____and____,which is used the least. The country that produces the most crude oil is____.

All organic molecules contain
Deforestation, removed, photosynthesis
Another thing that adds to the amount of carbon dioxide in the atmosphere is____which involves cutting down large areas of forest. Usually these forests are harvested for their wood, or cleared to create farmland. The reason this increases the levels of carbon dioxide in the atmosphere is because the trees would have____carbon dioxide from the atmosphere through the process of_____if the trees had been allowed to remain
Combustion
Besides cellular respiration, this process directly adds CO2 to the atmosphere
Cellular respiration, glucose, oxygen, carbon dioxide, water
Both consumer and producers release carbon dioxide into the atmosphere in a process called _____which is used to release the store energy in glucose. The reactants for this process are _____and_____and the products are _____and_____
cellular respiration
Both producers and consumers perform this reaction
detritus
Decomposers break down this
Using automobiles-combustion, using appliances that use electricity that comes from fossil fuels-combustion, cutting down trees: deforestation; burning down trees: combustion
Describe three things humans do to increase the amount of CO2 in the atmosphere
Long term is store carbon over a long period of time (only fossil fuels). Short term is store carbon temporarily (expect fossil fuels)
Differentiate between long term and short term carbon reservoirs
The solid lines show all the process that keep carbon moving through the part of the cycle that prevents it from becoming carbon dioxide. The dashed lines show all the process that release carbon dioxide
Explain the difference the solid lines in the diagram
Long, carbon reservoir
Fossil fuels act as a____-term____for storing carbon so that it is not likely to return to the atmosphere for a very long time normally
They incorporate carbon into their shells, and when they die the carbon in their shells sink to the ocean floor, and the carbon is trapped in the earth as limestone
How are mollusks, like calms, mussels, scallops, and other "shelled" organisms involved in the carbon cycle
Burned fossil fuels, releasing carbon into the air. Cut down/ burn huge areas of rainforest and other forests.
How have humans intervened in the carbon cycle?

Humans, however, have been doing things that add carbon dioxide to the atmosphere. When humans harvest fossil fuels and then burn them, this process is called____. During this process the carbon stored away in the fossil fuels gets released all at once into the____in the form of____. When forest are burned down, the process of____happens again with the same result as burning fossil fuels
