The amount of available energy changes between the trophic levels found in a food chain or energy pyramid. A food chain. Arrows point from one stage to the next. The stages are leaves, mouse, snake, hawk.

How would the amount of available energy differ in the trophic level of the mouse compared to the trophic level of the hawk?

a.
Available energy would increase from the mouse to the hawk.
b.
Available energy would decrease from the mouse to the hawk.
c.
Available energy would initially increase from the mouse to the hawk, and then decrease over time.
d.
Available energy would remain the same from the mouse to the hawk.

Is there any answer choices?

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.
