Can someone me plzzz the stability of a food web is determined by the stability of the : a. heterotrophs b. omnivores c. autotrophs

The stability of the food web is determined by the stability of the autotrophs.

Autotrophs are organisms that are able to produce organic substances from inorganic substances. Plants, for example, are autotrophic. Omnivores and heterotrophs are both dependent on autotrophs, making the stability depend on them.

An egg, or a sack of flour

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.
