A characteristic that helps an animal survive is called an adaptation.
Let's take a frog, for example.
It has strong leg muscles to be able to jump out of the water, snatch prey, and return quickly. It has cameoflague to hide itself from predators and sometimes even poison. It has a see-through eyelid of sorts that acts like goggles to let it see underwater and still keep debris out of its eye...et cetera.
The two processes are similar in that they both produce energy, albeit in two different forms. They are different in that photosynthesis assembles the glucose molecule, while cellular respiration takes it apart
It is the first option. Atmospheric nitrogen is very stable so there fore hard to react with. But bacteria contain molecules that can break the bond of nitrogen.
