All living things require energy in one form or another. Energy is transferred when one organism is eaten by another organism. A food web is an easy way to diagram the flow of energy in an ecosystem. The flow of matter and energy in
an ecosystem can also be represented in an energy pyramid. What is true of the flow of energy within an ecosystem?
Select ALL that apply.
A)
Energy flows from the bottom to the top of the pyramid.
B)
90% of the energy at one level is passed to the next level.
Only 10% of the energy is passed from one organism to another.
D)
The greatest amount of energy is found at the top of the pyramid.
E)
All organisms, directly or indirectly, get their energy from the sun.

This type of galaxy is an approximately ellipsoidal shape and a smooth, nearly featureless image. they are the largest single star systems, in the universe and are built by the collisions of many smaller galaxies.

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.
