Which one of the following plants use as a source for carbon dioxide?(

1.	Which one of the following plants use as a source for carbon dioxide?(a) Carbonate rocks(b) Calcium rocks(c) Fossils(d) Atmospheric CO2The question was asked during an internship interview.My enquiry is from Ecosystem in section Ecosystem of Biology – Class 12
Answer» The correct choice is (d) Atmospheric CO2 The explanation is: The plants use atmospheric CO2 as a source of carbon dioxide for food PRODUCTION. They PRODUCE food using photosynthesis. Photosynthesis is a PROCESS in which producers (green plants) in the presence of CO2, water, sunlight, and chlorophyll yield energy and oxygen is released in the FORM of gas.
