Use either the NASA or IPCC diagrams to complete the flow diagram below. It should represent the carbon sink and amounts in GtC (gigatonnes of carbon) and GtC/year (gigatonnes of carbon per year).
Fill in:
boxes representing sinks without names
sinks without carbon amounts
arrow lines without a directional arrowhead
arrows without flux amounts
