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____.

Atmosphere, plant, animal surface ocean, deep ocean, fossil fuels, soil

What are the 7 stops in the carbon cycle?

Use less fossil fuels, plant more trees, solar energy, wind energy, ocean wave energy

What can you do to stop global warming and climate change

This green pigment is found in plants and allow photosynthesis to happen

Carbon dioxide

CO2

Hydrogen atom bounded to a carbon backbone

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?

Combustion, atmosphere, carbon dioxide, combustion

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
