The arrows in the chart above represent the movement of carbon between four reservoirs: the ocean, plants, fossil fuels, and the atmosphere. the numbers in the blue boxes show the gigatons of carbon moving each year. more carbon is moving into the vegetation for photosynthesis than is moving out to the atmosphere via respiration. this means that the vegetation reservoir is a carbon sink, taking in more carbon from the atmosphere than it is releasing to the atmosphere. a carbon source is the opposite. a reservoir that behaves as a carbon source releases more carbon to the atmosphere than it takes in.
consider the statements listed here. do they accurately describe potential changes in the model? choose all that are correct.
deforestation would result in a decrease in the carbon sink.
increased use of alternative energy sources such as solar and wind energy would result in a decrease in released or sourced carbon.
if we consider non-industrialized countries, the model would remain the same.
if global warming continues, we would expect a change in the amount of carbon found in the ocean reservoir.
combustion of fossil fuels acts as a carbon sink.
all carbon in the atmosphere is made by humans.
which ones is it?
