Which sentence explains how energy is obtained during the process of photosynthesis? a) photosynthesis is a process that has serious implicaitons for the conversvation of our atmosphere b) photosynthesis tranform earth's early atmosphere by taking in some of the carbon dioxide released by volcanoes. c) photosynthesis is fueled by the sun d) plants and algae take in carbon dioxide from the atmosphere and released oxygen molecules

option C) Photosynthesis is fueled by the Sun.

Justification:

In brief, photosynthesis is a complex process that transforms the energy from the sunlight into chemical energy inside the bonds of the carbohydates of the plants.

Some specialized cells of the plants are able to catch the energy of the sunlight and, in a process that involves the reaction between carbon dioxide and water, transform that energy into chemical bonds to form glucose and oxygen.

Remember that the prefix photo means light, so photosynthesis stands for chemical reactions that use light.

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.
