Question

The plants which use cattle dung are called ___________
A) Thermal power plant
B) Gobar gas plant
C) Geothermal plant
D) Compost plant

Answer 1

Hint: Cow dung manure for plants is a high-quality organic matter fertiliser that helps to promote aeration and break up compacted soils. The manure can give the necessary fertility for your garden plants to develop and thrive.

Complete answer:
Let us analyze from the given options:
Option A) Thermal power plant: Thermal power plants transform thermal energy from primary fuels like coal into electric power. Hence, this option is incorrect.
Option B) Gobar gas plant: Gobar gas is produced at a gobar gas plant by bacterial fermentation of animal waste. It's made from biodegradable elements like manure, sewage, municipal trash, green waste, plant material, and crops, which are digested or fermented anaerobically. So, as manure, cattle dung is used in this plant. Hence, this option is correct.
Option C) Geothermal plant: Steam is used to generate energy in geothermal power plants. The steam spins a turbine, which turns a generator, which generates energy. Hence, this option is incorrect.
Option D) Compost plant: Compost is made up of a variety of materials that are used to enrich and enhance soil. It is often made from decomposing plant and food waste, as well as organic materials that have been recycled. Hence, this option is also incorrect.

Therefore, Option ‘B’ i.e, Gobar gas plant is the correct answer because it uses cattle dung in their plants.

Note: Biogas is a mixture of gases created by the anaerobic decomposition of organic matter in the absence of oxygen, chiefly methane and carbon dioxide. Environmental benefits include reduced emissions of greenhouse gases such as methane, CO2, and nitrous oxide. Organic waste from industry and households is recirculated in an environmentally responsible manner.
