carbon cycle Flashcards
when plants photosynthesise carbon atoms from CO2 become part of
glucose molecules
some of the glucose will be broken down by the plant in
respiration
the carbon in the glucose becomes part of the
carbon dioxide molecule which is released into the air
some of the carbon compounds in the plant will be
eaten by animals
the animals that eat the carbon compounds
respire releasing some of it back into the air as CO2
when plants&animals … will feed on them
decomposers
fossilisation occurs when
living things don’t decay fully
the carbon becomes part of the decomposers bodies so when they…
respire they release carbon dioxide into the air
fossil fuels are formed over
millions of years
fossil fuels are formed by a process called
locking in
when fossil fuels are burnt it’s called
combustion
during combustion, carbon dioxide is
released into the air
carbon dioxide goes into plants by
photosynthesis
when a plant dies the carbon goes to
decomposers
decomposers carbon dioxide goes to the atmosphere by
respiration
