Some bacteria produce methane during digestion. If the amount of these bacteria decreased a lot, the amount of methane in the atmosphere would decrease. What would happen to energy in the Earth system if this happened? If methane decreased, * 1 point there would be more energy in the Earth system and more energy absorbed by Earth's surface, because more energy would enter than exit. There would be more energy in the Earth system and more energy absorbed by Earth's surface, because less energy would enter than exit. There would be less energy in the Earth system and less energy absorbed by Earth's surface, because less energy would enter than exit.
