Answer: A. combustion
Explanation: During complete combustion, carbon and hydrogen react with oxygen (O2) to produce carbon-dioxide (CO2) and water (H2O). The carbon-dioxide produced is released into atmosphere and is utilized for carbon fixation and recycling.
Anaerobic situations will maximum possibly be generated in a herbal water gadget with low degrees of dissolved oxygen (DO) this is infected through pollution with excessive biochemical oxygen demand (BOD) values.
The required details for Anaerobic conditions in given paragraph
Anaerobic situations arise while the uptake or disappearance of oxygen is extra than its manufacturing through photosynthesis or diffusion through bodily shipping from the encompassing surroundings. Oxygen is typically fed on through microbial respiratory on account of the provision of natural material. Two examples of obligate anaerobes are Clostridium botulinum and the bacteria which stay close to hydrothermal vents at the deep-sea ocean floor. Aerotolerant organisms, which can't use oxygen for growth, however tolerate its presence. Facultative anaerobes, which could develop with out oxygen however use oxygen if it's miles present.
Most anaerobes require an surroundings with a low oxidation-discount potential (Eh gradient), which may be finished in affiliation with low pH, tissue destruction, byproducts from cardio bacterial metabolism, or low oxygen content.
