Answer 2

An autotroph is an organism that serves as a primary producer and this occupies the first trophic level in food chains. They take carbon dioxide and water from the environment and convert them the energy-rich carbohydrates (starch) with the help of sunlight (usually called photoautotrophs) and release oxygen. This happens in the chloroplast of the cells which have chlorophyll pigment that absorbs the sun's energy. Thus, the correct answer is option C.
