from where do plants obtain the initial carbon atoms that will be used in photosynthesis to make glucose a G3P B carbon dioxide c water D sunlight

Answer 1

Plants obtain the initial carbon atoms used in photosynthesis to make glucose from B) carbon dioxide. During the process of photosynthesis, plants take in carbon dioxide from the air through small openings in their leaves called stomata. This carbon dioxide is then converted into glucose through a series of reactions known as the Calvin cycle.
