ATP is vital for many different processes in both animals and plants. Bioluminescence is the biochemical emission of light by living organisms, such as fireflies and deep-sea animals. Bioluminescence occurs through a chemical reaction that produces light energy within the organism. The process of bioluminescence requires ATP to power the chemical reaction. What would happen if ATP was no longer available to these organisms that use bioluminescence to hunt prey? What do you think this would change in the ocean? Would these fish survive without bioluminescence? Think about if you had a limited amount of ATP available, would you be able to function as normal?
The bioluminescence that some species use to hunt prey is an adaptation that increases the organism's overall fitness. Without the ability to generate that light to attract prey, the species will have a much more difficult time obtaining its energy needs for survival and eventual reproduction. If the species is no longer surviving long enough to reproduce, the end result could quite possibly be the extinction of the entire species. That would be bad, but no species exists...
