The venomous lionfish is native to the Indian Ocean and the South Pacific Ocean. This fish has recently been introduced into the Atlantic Ocean. Which is the most likely consequence of the introduction of this invasive species? Native fish species will not be affected by the lionfish.
Native fish species will increase in population due to new prey species. Native predators will quickly decrease the population of the lionfish.
Native fish species will show reduced populations due to competition with the lionfish.

The answer would be c

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.
