Enzymes.
Enzymes are responsible to make reactions hard to take place, or even very unlikely to happen, to actually happen. They are proteins that have normally an active binding site where molecules may connect to and preform the reaction. The necessary energy to make a reaction occur is less when aided by enzymes and that's what makes of them catalysts so that reactions may occur even when in lower temperatures.
I believe it is temperature or rainfall. All of the factors are improtant but temperature comes first, cuz the temperature can also determine the air, and soil doesn't make a difference. Longitude doesn't have to do with an ecosystem.
Some of them include kimchi, sauerkraut, kefir, tempeh, kombucha, and yogurt.
I think the correct answer from the choices listed above is the last option. The pollutant that <span>is transferred from soil to water by fertilizer runoff from farms and leaky septic tanks would be nitrates. This pollutant is present in fertilizers and are produced from reactions in a leaky septic tanks. Hope this answers the question.</span>
C) is definitely the bacterium!
A) look like a paramecium with it's flagela and vacuole
B) is a plant cell with chloroplasts
D) could be an animal cell, plant, or fungal since it has a nucleus
**remember: bacteria lack ALL membrane bound organelles: nucleus, mitochondria, chloroplasts, E.R.!!
