> An autotroph is an organism that can produce its own food. Which of thefollowing is an autotroph? And the answer: Azalea.Photo credit: Getty ImagesOrganisms can be categorized into two main groups:autotrophs, which produce their own food, and heterotrophs, which consume otherorganisms for food. Plants fall into the first group, as they produce their ownfood through photosynthesis. Mammals, birds, and reptiles are examples of thesecond group, which rely on others for food.While plants and animals can be broadly distinguished between "producer" and"consumer," each category comes with qualifications and distinctions that canbecome very specific. For example, while heterotrophs are generally the"consumer" of the food chain, herbivores (or organisms that eat plants) occupythe second level of the food chain. Meanwhile, carnivores and omnivores(organisms that eat meat) occupy the third level. Both of these primary andsecondary consumers are considered heterotrophs.There is also a third type of heterotrophic consumer: a detritivore. Theseorganisms obtain their food source by feeding off dead and decaying plants andanimals. Creatures such as worms, fungi and insects are essential to ecosystemsin that they provide the recycling of nature’s waste. Autotrophs create energy through photosynthesis. The chlorophyll in theautotrophs allows them to capture and use the sun’s energy to power theirsystems. Heterotrophs are unable to photosynthesize due to their lack ofchlorophyll. But that is not to say that heterotrophs do not benefit from photosyntheticprocesses. Heterotrophs depend on the process for oxygen, which is produced as abyproduct of photosynthesis. Further, photosynthesis nourishes the autotrophsthat heterotrophs depend on to survive. While carnivores may not directly dependon photosynthetic plants to survive, they do depend on other animals thatconsume photosynthetic plants as a food source.
