Answer 2

There are two ways in which animal dung can be used as a fuel:

(i) To heat animal dung in the form of cakes after drying them.

(ii) Anaerobic degradation of animal dung to produce useful fuel called biogas. Second method is a better way of using animal dung as fuel because it is more efficient.

Heating animal dung in the form of cakes after drying them, when it is dried, it will be easy to buy and use. but if we use bio gas then it will be easy to mix with the soil.

ps: you can chose which ever u feel like for the better one
