The researchers set up experimental and control microcosms, or small artificial ecosystems, to measure the release of minerals from rocks. first, they placed rock fragments of volcanic origin, either granite or andesite, into small glass containers. then they made a suspension of water and macerated (chopped and crushed) moss of the species physcomitrella patens. they added this mixture of water and moss to the experimental microcosms. for the control microcosms, they filtered out the moss and just added the water. after 130 days, they measured the amounts of various minerals found in the water in the control microcosms and in the water and moss in the experimental microcosms. how did the setup of the control and experimental microcosms differ?
