An autotrophic (or self-digestive) organism is an organism that makes its own food with no eating, by using its oral bacteria for digestion. All green algae, all bacteria and some protists are autotrophic. Some eukaryotic cells such as plant prokaryotes are unaided, i.e., they have no need of an external digestive system. Deamination of food is also carried out by an autotrophic digestive organ. Some organisms may only have an immune system so that they can consume other nutrients normally, whereas others have an immune system and other organs such as the tongue, colon, bladder, etc.
The anaerobic environment: that exists in which autotrophic organism lives is similar to the one that aerobic organisms (oxygen-requiring organisms) live in. The process of photosynthesis in the case of green plants and bacteria occurs when there is an accumulation of carbon dioxide and water. Photosynthesizing an organism requires the assistance of an enzyme that is triggered by the sunlight or light energy. The absence of sunlight results in the production of energy by non-photosynthesizing organisms. This process of photosynthesis is an important part of aerobic life on Earth.
Many different types of Photosynthetic Organisms exist: The Photosynthesizing Eukaryotic Organism is the most common Photosynthetic Organism found in nature. This is also called the Photosynthetic Complex. Certain species of plants and animals have the ability to Photosynthesize. Photosynthesis in lower life forms such as bacteria and yeast is very important. Photosynthesis in higher life forms such as vertebrates, plants and fungi have important roles in the Earth’s ecosystems.
Photosynthesis is a means for living organisms: to consume food and create energy for their own survival. This process continually takes place within all living organisms no matter what type of organism they are. The end result of Photosynthesis is the accumulation of carbon dioxide and water, which are converted into food for the plant or animal. There are two types of Photosynthetic Organisms; primary and secondary autotrophy. Primary autotrophy is any organism that can create energy or use the energy it itself; secondary autotrophy is an organism that requires a cue from sunlight or the light and other external factors to Photosynthesize.
An organism’s level of activity: in the food chain determines whether it is considered to be an autotrophic or a trophic level. An autotrophic organism is any organism that uses its own nutritional resources to create energy and only needs the energy from other organisms to survive. A trophic level is any organism that creates more than it uses, such as an insect that building nest boxes and other structures on the garden soil.
The earthworms are at the top of the food chain: They are considered to be primary consumers, while the other organisms at the base of the food chain are considered secondary consumers. When it rains, the earthworms go back to the bottom of the food chain, while the other species continue on their journey up the food chain to become the primary producers.
These food producers include the bacteria and other life forms that are part of the ecosystem.
