Answer from: alienfacetimelol

Biodiversity is the different population organisms present in a certain area. It is the variety of life forms.

Explanation:

Biodiversity means a variety of life forms present on earth. It is the number of different species living in an area. There are so many varieties of life on earth. They are found in different environments such as in the land, water, and in the air also. They form different animal groups such as animal kingdom, plant kingdom, and the microbial life. For example, in a pond, there is several frogs and fishes are living and they form fish populations, frog population, etc. This different population in an area forms the biodiversity. Each organism of biodiversity is important because they maintain the balance of the environment.

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.
