Which of these is the best example of a positive feedback loop in earths climate system? a. high precipitation results in increased plant growth, lowering co2 b. as the number of plants increases, the amount of co2 increases c. as climate warms, co2 increases because plants remove less of it d. high clouds have a high albedo and reflect solar energy back into space

Option A. is correct.

Hope it helped!

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
