Answer 1

1) Bacteria responsible to enrich nitrogen in the soil is Cyanobacteria, Anabaena and Notoc.

2) Symbiosis is the relationship between two organisms in which they live together by sharing resources with each other. E.g. Alage and Fungi.

3) Farmers mostly use organic manure made up of dead and decayed biodegradable waste from home.

4) Saprophytes first releases saliva on the dead and decayed things which digest them. Then they swallow and digest the nutrients present in them.
