I would think Carbon monoxide and water.
Abiotic: biotic
rocks animals
water plants
air fungi
sunlight bacteria
minerals
soil
It is easiest to tell if a solution is saturated if there is residue on the bottom. If it crystallized, the solution is saturated. If it is a supersaturated solution, there will not be crystallization unless more of the solute is added, at which point all of it will crystallize.
Soil can get swept away into the water (by wind, gravity, rain, etc) and can increase the water level of the body of water.
Another thing is that if the soil was infected with pesticides from farmer's crops then the toxins that were in the soil can pollute the body of water. hope this helps!!
