How and organism goes extinct if it cannot adapt

          If an organism cannot adapt to its environment it will die and if its species cant adapt, then its goes extinct. If a frog is trying to hide from a predator and doesn't blend in, the predator is going to eat that frog first. if a fish isn't adapted to living in cold water and it gets put in Antartica, it will die and make that species go extinct, but, if it is adapted it can survive and carry on its traits to its offspring so it can survive.if the environment changes, like if it starts becoming warmer on an island, then the birds have to adapt to live in a warmer environment  or they will become extinct.
