1a to determine the present is micro organisms in a soil sample

II. Lime water in flask I will turn Micky and lime water in flask II will remain clear.

II. It shows that there are presence of micro organisms in the soil sample in flask I and there are respiration which turn lime water Micky.


Iv i. Aids decomposition of organic matter

II aids germination of seeds
1ai)

To show the presence of living micro-organisms in the soil


1aii)
