A drought occurs in an environment with a large plant population. Which element of natural selection is most likely to enable part of the population to survive and reproduce?
the potential for the plant population to produce more offspring than can survive
a change in climate conditions
competition with other plant and animal populations for finite water resources
some individual plants inherited traits that enable them to survive a drought

The appropriate answer is d. all of the above. Water, air and natural habitats can be classified as natural/physical resources. Physical resources are those that occur naturally in the environment. Natural habitats such as forests or coral reefs can be preserved by designating this areas as national reserves. Monitoring and reducing the the release of substances in the air or water are methods of conservation.
