The graphs below show the changes in crab color at one beach.
Which of the following is most likely to have caused the change in the distribution?
A new predator arrived that preferred dark-tan crabs.
A new predator arrived that preferred light-tan crabs.
A change in beach color made medium-tan crabs the least visible to predators.
A change in beach color made medium-tan crabs the most visible to predators.
Which of the following best illustrates natural selection?
An organism with favorable genetic variations will tend to survive and breed successfully.
A population monopolizes all of the resources in its habitat, forcing other species to migrate.
A community whose members work together utilizing all existing resources and migratory routes.
The largest organisms in a species receive the only breeding opportunities.
The process where two species evolve in response to long term interactions with each other (for example clams having harder shells so that it is more difficult for a crab to break them) is called...
