Species like fish and turtles have many predators. These species produce more offspring than will survive. Which of the following correctly addresses an advantage and disadvantage of the overproduction of offspring? Species have an increased chance of survival and parents are able to care for the young.

Competition of resources in the environment is reduced and species have a decreased chance of survival.

Overproduction of one species can threaten another species and species can become resistant to medicine.

Populations of species have increased genetic variation and competition for resources in the environment is increased.
