Despite the efforts made by wildlife conservationists, many plants and animal species remain at risk. In biology, what is the term for the death of an entire species?

Extinction is the termination of an organism or of a group of organisms under natural or human-induced circumstances. Experts estimate that between 0.01 and 0.1% of all species become extinct each year. To put the low number into perspective, that means between 200 and 2,000 extinctions occur every year based on the roughly 2 million different species on our planet.
