Biogas produced by fermentation of manure, sewage, cattle dung, etc predominantly comprises
1 Methane, nitrogen and hydrogen
2 Methane and carbon dioxide
3 Methane and carbon monoxide
4 Methane and nitric oxide
Explanation:
Biogas is a mixture of gases. Biogas is composed of methane- $50-70 \%, \mathrm{CO}_2 30-40 \%$, traces of nitrogen, hydrogen sulphide and hydrogen. Methane and $\mathrm{CO}_2$ are major component of biogas.

By anaerobic process, the cow dung is used to produce :
1 Methane
2 Butane
3 Ethane
4 Propane
Explanation:
Biogas is a mixture of gases [containing predominantly methane $\left(\mathrm{CH}_4\right)$ ] produced by anaerobic bacteria through fermentation of animal dung (or biomass).

Bio gas production from waste bio mass with the help of methanogenic bacteria is :
1 multi step process
2 one step process
3 two step process
4 three step process
Explanation:
Biogas is produced by anaerobic bacteria that degrade organic matter in 3 stages - solubulization, acidogenesis, methanogenesis.

Pollution from animal excreta and organic waste from kitchen can be most profitably minimized by
1 Storing them in underground storage tanks
2 Using them for producing biogas
3 Vermiculture
4 Using them directly as biofertilizers
Explanation:
Pollution from animal excreta and organic waste from kitchen can be most profitably minimized by using them for producing biogas. Biodegradable wastes like animal excreta and organic waste from the kitchen can be used in biogas plants to generate biogas and manure. These wastes release methane and other gases as a result of anaerobic microorganisms. Biogas contains methane in bulk and other gases like $\mathrm{CO}_2, \mathrm{H}_2$, $\mathrm{N}_2$ and $\mathrm{O}_2$. Biogas is a cheap source of fuel and the manure can be used as a cheap fertilizer.
