Explanation:
(i) Answer. Biogas is a type of biofuel that is naturally produced from thedecomposition of organic waste. When organic matter, such as food scraps and animal waste, break down in an anaerobic environment (an environment absent of oxygen) they release a blend of gases, primarily methane and carbon dioxide.
(ii) Answer: biogas is obtained which contain 76% of methane and is used as a fuel by us.
(iii) A decomposer is an organism that decomposes, or breaks down, organic material such as the remains of dead organisms. Decomposers include bacteria and fungi. These organisms carry out the process of decomposition, which all living organisms undergo after death.
(iv) Natural gas is a fossil fuel – but it's cleaner and more efficient than other traditional fuels. ... For example, when natural gas is burned, it produces 45 percent less carbon dioxide than coal, 30 percent less than oil and 15 percent less than wood.
(v) A fuel is any material that can be made to react with other substances so that it releases energy as heat energy or to be used for work.
