Question

In a survivorship curve,a type III species,like most insects and plants,is a species that has
A) an extremely long life span.
B) an equal probability of dying at any age.
C) the highest probability of dying at a very young age.
D) a strong possibility of becoming extinct in a relatively short period of time.
E) the highest probability of dying as it reaches its maximum life span.

Accepted Answer

Type III species have a high probability of dying at a very young age, often due to predation, disease, or other environmental factors. This results in a steep decline in survivorship early in life, followed by a slower decline for those individuals that survive past the vulnerable stage. They do not have an extremely long life span (A) or an equal probability of dying at any age (B). While extinction is always a possibility, it is not a defining characteristic of a type III species (D). Finally, maximum life span is not typically reached by type III species, so they do not have the highest probability of dying at this stage (E).
