Answer 7

Animals die all the time, sometimes in large numbers. However, at the same time plenty more are being born. Thus, most species offset the death rate with many new births. When a species' equilibrium is thrown off, though, and the death rate eclipses the birth rate, it begins down a slippery slope toward dying out completely. When a plant or animal dies out to the point at which it has no living specimens either in the wild or in captivity, it's considered to be extinct.
