3. These events are listed in the order in which they occur. Highlight the missing word in each event. a. Carbon dioxide enters the ( almosphere I hydrosphere i geosphere? biosphere ) from volcanos or from the burning of fossil fuels. b. Carbon dioxide dissolves into the ( Earth / ocean / atmosphere/plants ). G. Carbon dioxide is used by plankton during photosynthesis to make organic molecules containing ( lead / carbon / argon / chlorine ) d. Organisms die and drift down to the ( benthic zone / open ocean? intertidal zone / photic zone ). e. Carbon builds up in layers at the bottom of the (geosphere / atmosphere / ozone layer i ocean ). f. (Ocean crust / ozone / agricullural runoff / fertilizers ) carrying carbon is subducted into the Earth. g. Subducted ( ocean sediments / atmosphere/ waler/ anthropocene) melt as they are pulled down into the Earth. h. From deep in the Earth, magma carrying carbon is returned to the (hydrosphere/ geosphere / anthrosphere/ atmosphere ) by volcanos.
