There is an algal bloom in a lake in a populated area. as the leading scientist for the water department, what is the most important thing to do, based on scientific evidence about such blooms?

It is important to detect and characterize first the algal species by obtaining water samples from the lake. This is a critical and very important step for prevention, control and mitigation of algal blooms. There a number of methods for this such us microscopic methods, molecular probes and remote sensing techniques.

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.
