Substances made of carbon, hydrogen, and oxygen include sugars (like glucose and sucrose), fats (such as triglycerides), and proteins (amino acids). These substances are essential for providing energy, building structures in cells, and regulating various functions in living organisms.
Something that is "biodegradable" is made form substances that will break down completely and quickly when exposed to sunlight and moisture (and possibly micro-organisms). A good example is "packing peanuts" made from cornstarch.
Biotechnology is used in sewage treatment plants to aid in the breakdown of organic matter by microorganisms, leading to cleaner water that can be discharged back into the environment. Biotechnological methods can also be used to remove pollutants and harmful substances from sewage, improving the efficiency and effectiveness of wastewater treatment processes.
fungal has cell walls made of chitin '' lack chlorophyll, so they feed themselves by being saprophytes,shich live off dead organisms, or parasites,which live off living organisms.
