Answer:
False
Explanation:
Photosynthesis organisms are the ones that use the energy of sunlight to fix the atmospheric CO2 into organic sugars. These organisms can make their own food. Chemosynthetic organisms derive the energy by oxidation of fuels, rather than from sunlight and make the organic compounds. Since both photosynthetic and chemosynthetic organisms can make organic food by themselves, they are autotrophs.
They do not depend on other organisms for their organic nutrients. These organisms serve as primary producers as they produce organic nutrients for themselves. Examples of photosynthetic organisms are the green plants while the chemosynthetic organisms nitrifying bacteria.
