What can scientists use to determine the type of plant an organism consumed? a. carbon 13 and carbon 12 b. index fossils c. radioisotopes d. carbon 14?

Carbon 12 and Carbon 13

In plant, the ratio of carbon 12 and carbon 13 isotopes is different depending upon the plant photosynthesis. The distribution of these isotopes in plant tissue can indicate the path way of carbon metabolism that is either C3 fixation or C4 fixation. This help scientist to know if the plant consumed by organism is C3 plant or C4 plant by measuring the isotopic signature of their collagen and other tissues.

This can help scientist know which plant is consumed by animals.
