These bacteria are anaerobic, which could be purple or green. BRALEY SA Sr, KINSEL NA, LEATHEN WW. Plants, algae, and bacteria have the ability to use sunlight, water, and carbon dioxide (CO2) and convert them into organic compounds necessary for life in a process called photosynthesis. aging.
Reason: Chemosynthetic autotrophic bacteria oxidise various inorganic substances to obtain energy. 5. (i) Photoautotrophic bacteria (Photoautotrophs): They use solar energy for the synthesis of their own food. However, the latter use the energy of sunlight. to supplement their energy requirements. Assertion: Chemosynthetic autotrophic bacteria play a great rolie in recycling nutrients like nitrogen, posphorous, iron and sulphur. I just don't understand this and it's very complicated but you have to use your brain in order to understand but once again I don't understand good job on the hub though it was great I'm not the only one that didn't understand it but I think that if you gave examples to understand I would get it better the only reason I am still on this is because it is a very good hub one thing that I also like about this is that it gave pictures and information about the same subject. The organic molecules produced by phototrophs are used by other organisms known as heterotrophs, which derive their energy from phototrophs, that is to say, they use the energy from the sun, indirectly, by feeding on them, producing the organic compounds for their subsistence. (2006). Catabolism for energy it is the process of obtaining energy, and 2. Acidithiobacillus* Bacteria* Carbon Cycle* Chemoautotrophic Growth* Iron/metabolism* Nitrobacter* Substances. Heterotrophs: They are depend on other organisms for food. and convert them into organic compounds like carbohydrates, proteins, etc. examples of autotrophic bacteria include. Chemosynthesis occurs in environments where sunlight is not able to penetrate, such as in hydrothermal vents at the bottom of the ocean, coastal sediments, volcanoes, water in caves, cold seeps in the ocean floor, terrestrial hot springs, sunken ships, and within the decayed bodies of whales, among many others. Extremophiles are organisms that thrive under conditions that are considered detrimental for most organisms. The chem osynthetic support of life and the microbial diversity at deep-sea hydrotherm al vents. They utilize simple inorganic compounds like carbon dioxide, water, hydrogen sulfide, etc. An organism that produces organic molecules from organic carbon is classified as a chemoheterotroph. Autotrophic bacteria synthesize all their cell constituents using carbon dioxide as the carbon source. The bacteria that are found there can synthesize methane by combining hydrogen and carbon dioxide. Chemosynthetic bacteria are organisms that use inorganic molecules as a source of energy and convert them into organic substances.
