For 10 points, identify this compound absorbed by plants for photosynthesis, whose solid form is called dry ice.
Over 1700 died in the 1986 Lake Nyos disaster after a limnic eruption released this substance, whose solid form was first described by Charles Thilorier. The subject of the Kaya identity and Keeling Curve, this substance is a reactant along with hydrogen in both the Sabatier and Bosch reactions. Also known as carbonic anhydride, this compound can be obtained via air distillation and, along with water, is a product of the combustion of hydrocarbons.
