Devise an experiment to test that microorganisms need optimal temperature, air, and moisture for their growth. Class 8

Answer:

Make a set-up of 3 bread slices :

1. Slice A: Warm, moist environment (near sink)
2. Slice B: Dry environment (sealed container)
3. Slice C: Cold environment (refrigerator)

Observe the slices after 3 days :

Slice A will have maximum microbial (fungal) growth.

Conclusion: Microorganisms grow best when temperature, moisture, and air are ideal/ perfect.
