This picture shows the united states arctic national wildlife refuge, a large portion of alaska that is protected from human activities that would affect living things in the area as well as nonliving resources that support living things. even though oil and other resources in the area could be collected and sold by humans to increase american wealth, construction is prohibited in the area. the most complex level of organizational hierarchy in the arctic national wildlife refuge that is preserved is the population of brown bears in the area. every species of fish in the area. every ecosystem in the area. the biosphere that includes alaskan life.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
