It is called organism to the group formed by the organs of a living being, with the laws that organize its operation and its interrelationships. Autotroph , on the other hand, is the qualification that a living being receives that can create its own organic matter through inorganic elements.
The autotrophic organisms therefore they are in a position to develop organic matter from an inorganic substance . This makes a difference with respect to heterotrophic organisms , which must feed on other beings to achieve, in this way, the organic matter synthesized.
The food that these organisms have is called, as expected, of autotrophic nutrition . Since they alone can synthesize the substances they need for proper metabolic functioning through inorganic substances. This means that they should not feed on living beings.
The vegetables that appeal to the photosynthesis to get Energy from the light they are part of the group of autotrophic organisms. The same can be said of those bacteria They resort to the action of oxidizing certain inorganic materials to generate the energy they need.
Carbon is the essential chemical element in the composition of a living being. In the case of autotrophic organisms, the so-called Calvin cycle It allows carbon fixation through a metabolism process. Within the group of autotrophic organisms, we can also find photoautotrophs, which are those that use light to achieve the synthesis of organic components, and chemoautotrophic organisms, which develop different chemical reactions with the same objective.
The importance of autotrophic organisms for life
The role that autotrophic organisms play in the development and stability of life on the planet is extremely relevant. That is why it is so important to take care of the environment and keep the green areas of the planet intact to ensure a long existence on Earth.
Due to their ability to transform something inorganic into organic, autotrophic organisms constitute a key link in the food chain : its metabolism allows the development of itself and other living beings. But this is not all, if they did not exist life would not have been conceived as we know it today so its importance exceeds the limits of reality.
Thanks to the presence of these organisms capable of creating their own food it was possible that others arose that could take advantage of them for their subsistence (heterotrophs). And it is that from the origins of life these other organisms obtain the energy from the work of degradation and synthesization that the first ones do and that store in sor interior. Within the group of heterotrophic living beings we can mention the species belonging to the fungi kingdom and to the animal kingdom.
If there were no photosynthesis, we should assume that life would not exist as we know it, hence the great relevance of plants, fundamental individuals within the group of autotrophs. Through the process of photosynthesis, plants transform the energy of the sun and minerals into energy compatible with the survival of other living beings, chemical energy.
Another great difference between autotrophic and heterotrophic organisms is that the former do not need to travel to obtain their food because they can take advantage of sunlight and the properties of their environment to produce their energy. On the other hand, heterotrophs usually need to move to get their energy, which they obtain from other living beings, many of them, as is the case of a rabbit feed on autotrophic organisms (grass), others from other individuals belonging to the group of the heterotrophs, as is a lion of a gazelle.
