Question

A species of butterfly lives in a warm climate. The butterflies feed on the nectar of tropical flowers. Birds eat the butterflies, and they prefer to eat the butterflies with brighter wings.

What would most likely cause this species to become extinct?

a mutation resulting in darker wings
a decrease in the birds that eat the butterflies
the destruction of the butterflies’ environment
overproduction of butterfly offspring

Answer 1

the destruction of the butterflies’ environment

Reason: destroying their tropical habitat would remove nectar sources and breeding sites, causing population collapse. A mutation for darker wings would likely reduce predation (not cause extinction), fewer birds would reduce predation, and overproduction alone doesn't drive a species extinct.
