What is the Meaning of Autotrofo

We understand by autototrofo to all organisms that have the ability to make their own food from inorganic substances such as the non-living elements of the planet (electricity, water, etc.). Most common and important autotrophic organisms include plants since they make their own food synthesis, using elements such as water and sunlight to produce their food. The word autotroph comes from the Greek language, for which auto means 'same', 'one's own ' and trophe 'nutrition', resulting in "nutrition carried out by oneself". Beings or autotrophs are perhaps the simplest in the world of the living animals and the human being needs to feed on other compounds in addition to consuming the first as food itself. For humans autotrophic elements such as water or sunlight (from which you perform photosynthesis or synthesis of light) are essential since it is only from them that they can produce their own food and continue to grow.
In the food chain, the autotrophic beings are the first links and are, it needless to say, very important so that the rest of the agencies can participate in it. Since the autotrophs are the only beings in take power directly from the atmosphere to feed, the other beings (heterotrophs) need the process of synthesizing the first made in a natural way. Thereby, animals and human beings consume plants to receive energy already processed. At the same time, carnivorous animals like humans, cats or wolves used their herbivorous prey to receive the nutrients and energy that can generate an autotroph organism.
In addition to the plants and vegetables, seaweeds are also considered autotrophs beings but performed a kind of synthesis known as chemosynthesis, made from the fixation of carbon and other elements.
