First of all, the idea that autotrophs are nuclear organisms is not allowed. Prokaryote is an autotrophic organism. Autotrophic organisms are organisms that survive and reproduce by inorganic nutrition. Organisms that assimilate carbon by using energy obtained from chemical dark reactions such as respiration or photochemical reactions are called chemoautotrophs and photoautotrophs respectively. Prokaryotic cells can carry out aerobic respiration. Some prokaryotes, such as nitrifying bacteria and rhizobia, have no mitochondria, but contain a full set of enzymes related to aerobic respiration, which are distributed in the cytoplasm matrix and cell membrane, so these cells can carry out aerobic respiration.

Second, autotrophic organisms are also called producers. It mainly includes green plants and many microorganisms. They can make use of sunlight, carbon dioxide in the air, water and inorganic salts in the soil to produce organic matter through biological processes such as photosynthesis, and provide material and energy for the lives of various organisms in the ecosystem. Producers' materials are transferred to consumers by being consumed by consumers, and at the same time, some energy is transferred. Prokaryotes are organisms composed of prokaryotic cells, including cyanobacteria, bacteria, archaea, actinomycetes, rickettsia, spirochetes, mycoplasma and chlamydia. Prokaryotes are cells with basic cell structure, including cytoplasm, cell wall, cell membrane and flagella. Cell walls do not include all prokaryotes, with one exception: all prokaryotes have cell walls except mycoplasma; Mycoplasma is the only prokaryote without cell wall.

3. Autotrophic organisms generally have no digestive function, so they cannot swallow other organisms (such as animals and fungi). Therefore, autotrophs use other methods to maintain life, such as photosynthesis used by plants. However, plants still need water, visible light and carbon dioxide in the process of photosynthesis, which does not mean that plants are autotrophic biota, because these three conditions are the basic conditions of life. Prokaryotes are too small to be seen by the naked eye and must be observed under a microscope. Most prokaryotes are aquatic. They can breathe aerobically underwater and are the earliest single-celled animals on earth. The smallest prokaryote is mycoplasma. Prokaryotes in fungi include bacteria, actinomycetes and fungi; Fungi are divided into yeast, mold and edible fungi; Bacteria and actinomycetes belong to prokaryotes, while yeasts, molds (Mucor, Aspergillus and Penicillium) and edible fungi (such as tremella, auricularia auricula, Ganoderma lucidum and mushrooms) belong to eukaryotes. Prokaryotes in algae include cyanobacteria (such as chromococcus). Nostoc commune. , tremella species. And Spirulina. Red algae (such as laver and seaweed) and brown algae (such as kelp) belong to eukaryotes.
