Decomposition
Yes. Viruses are made of the same substances that living organisms are.
Sediment, compressed dead solid organisms.
Sediment, compressed dead solid organisms.
Vaccines for the prevention of the specific viral infection can be made with inactive "dead" viruses. They are also made with live, but attenuated (weakened), viruses. See more below about vaccines.
Oil comes from fossil fuel and oil is mainly dead plants organisms.
Dead organisms that were living million / billion/S of years ago.
Limestone is a sedimentary rock that is often formed from the remains of dead marine organisms such as shells and coral. This type of rock is composed mainly of calcium carbonate.
Coral is not made by us.It is made up of exoskeletons of dead minuscule organisms found in the sea which form reefs.
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.
Decomposers, such as fungi and bacteria, break down the remains of dead plants and animals. They play a crucial role in nutrient cycling by breaking down complex organic materials into simpler substances, which are then made available to other organisms in the ecosystem. This process not only recycles nutrients but also helps maintain soil health.
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.
