INDIAN GEOGRAPHY

Detailed explanation-1: -During anaerobic digestion of organic waste, such as in the producing biogas, which one of the following is left undergraded ? Anaerobic bacteria digest animal waste and produce biogas .

Detailed explanation-2: -Biogas is a mixture of methane, CO2 and small quantities of other gases produced by anaerobic digestion of organic matter in an oxygen-free environment.

Detailed explanation-3: -Waste-to-energy Animal manure, food scraps, wastewater, and seware examples of organic matter that can generate biogas through anaerobic digestion. Due to the high methane content (typically 50-75%), biogas is flammable, and therefore produces a deep blue flame and can be used as an energy source.

Detailed explanation-4: -Biogas is produced using animal dung, kitchen waste and agriculture waste.

Detailed explanation-5: -Biogas is an environmentally-friendly, renewable energy source. It’s produced when organic matter, such as food or animal waste, is broken down by microorganisms in the absence of oxygen, in a process called anaerobic digestion.
