Which one produce gas by decomposing the gobar (Dung) in gobar gas
1 Fungus
2 Virus
3 Methanogenic bacteria
4 Algae
Explanation:
Gobar gas is a term used for the biogas in India. Biogas is produced by the breakdown of the organic matter in the closed container in the absence of the $\mathrm{O}_{2}$. Biogas is an alternate source of energy produced by anaerobic breakdown or digestion of biomass such as animal excreta and kitchen waste with the help of methanogenic bacteria. - Biogas is made up methane (50-70\%), $\mathrm{CO}_{2}(30-40 \%)$ with traces of nitrogen, hydrogen sulphide and hydrogen.

Azolla is used in the cultivation of
1 Maize
2 Sorghum
3 Wheat
4 Rice
Explanation:
Azolla is a nature's gift for rice cultivation and has tremendous other agricultural use. - Azolla substaintially increase the amount of nitrogen fertilizer available to growing rice and it has been used for thousands of year as a green nitrogen fertilizer to increase rice production.

Anabaena is associated with Azolla
1 Stem
2 Leaves
3 Roots
4 Flowers
Explanation:
Azolla is a free-floating water fern and has agronomic importance due to its ability to fix nitrogen. - Azolla is also called the mosquito fern. - Anabeana forms a symbiotic relationship where its leaves in the ovoid cavities of the dorsal leaves in the term and is connected to the external surrounding through pores.

Plant pathogenic bacteria are mostly
1 Gram + Non spore forming
2 Gram - Non spore forming
3 Gram positive spore forming
4 Gram negative spore forming
Explanation:
Several species of bacteria are pathogenic and cause disease but plant pathogenic bacteria are mostly gram -ve non spore forming. - The gram stain characterises bacteria based on the structural characterstics of their cell walls. - While bacteria are known to form endospores, these are rarely plant pathogenic. - The conidiophores and sporangiospores are reproductive spore formed only in Streptomycetes, some of which are plant pathogens.
