Question
Water and this molecule are the typical components of structures indicated by bottom-simulating reflectors at the base of a "stability zone." Organisms that consume this molecule via AOM may reside in a transition zone of sulfate and this compound. Microbial production of this molecule may have promoted the P–T extinction event. A "gun hypothesis" describes this molecule's release from underwater (*) clathrates. This is the most impactful molecule released from the "active layer" in a seasonal positive feedback loop that accelerates its release from melting permafrost. This common greenhouse gas is 30 times more potent than CO2. For 10 points, name this primary component of natural gas, a hydrocarbon with formula CH4. ■END■
