Definitions:

Slow Reproduction Rate

A characteristic of some species that have fewer offspring and longer gestation periods, often leading to vulnerability and risk of extinction.

Biological Extinction

The disappearance of an entire species from the face of the Earth, which occurs when the last individual member dies.

Vulnerable

A status indicating that a species is at high risk of endangerment in the wild, often used in conservation contexts to prioritize efforts.

Keystone Species

A species that has a disproportionately large effect on its environment relative to its abundance.
