Describe how the barred owl population is having a negative effect on the spotted owl population

 Barred owl population filled the niche of a spotted owl and the rapid expansion of the barred owl into the range of the spotted owl occurred. The barred owls are a little bit larger, more aggressive and have a wider variety of prey species than spotted owls. Also, barred owls nest more often and successfully, thus producing more young than do spotted owls. This gives barred owls a competitive advantage over spotted owls and as a result, spotted owl populations are rapidly declining in many areas.

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.
