What is the difference between protection and preservation?

Definition one.

An animal need protection in order to survive.

Either we humans protect it, or it protect itself.

Hunters would preserve an animal after killing it so that they can keep it on display.

Definition two.

Protection and Preserving is closely related.

We need to protect this species. It might become extinct if we do not preserve it.

Preservation is a stronger form of protection.

Protection can some times fail but we would go to "extremes" in order to preserve spieces from extinction.
