Light-independent reactions (dark reactions). Light reactions need light to produce organic energy molecules. Dark reactions make use of these organic energy molecules.
They all have instruments to "uncouple" oxidative phosphorylation from electron transport framework by giving an option system to protons to come back to the mitochondrial grid. As protons enter the lattice without going through ATP synthase, their vitality is discharged as warmth. So these produce warm by uncoupling those two procedures.
What would happen is if there was no ecosystem in biodiversity every organism would become effected in such a impactful way. It would Decrease population in animals and Humans
I really hope this helped :)
#1 PROBABILITY is the likelihood that a given event will occur.
I'm not sure on #2, Sorry
