Abird species is introduced in an area. the bird species feeds on the same seeds as the bird species that already occupied the area. what is the most likely effect on the original bird species? a. the population of the original bird species will decline to zero. b. the population of the original bird species will remain the same. c. the population of the original bird species will increase. d. the population of the original bird species will decrease.

I think the best option, looking at the answers is D

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.
