You are part of a team that was testing the new Mars Perseverance rover in the Atacama Desert. On Day 1 you explored this pristine site and saw that there was a high concentration of oxygen, nitrate, and sulfate. The sand grains in the study site were also covered in iron and manganeses oxides. On Day 2 one of the local mining companies had an accident and spilled thousands of gallons of gasoline on the same site you were studying (unfortunately this happens). Describe the succession of all possible metabolisms of the bacteria associated with the aquifer based on the availability of nutrients listed above from the area closest to the gas spill and outward.  You then return several weeks later what is the most likely metabolism to be at the origin of the contamination site (at the spot where the gas was first dumped)
