Answer 2

Answer:

In the presence of sufficient moisture, the microscopic spores of fungi found in the air germinate on gunny bags, wooden items, cotton fabric, leather and so on. The fibres of the fungus (fungal hyphae) dig deep into the material to obtain nutrition and to reproduce. Hence, the gunny bags and leather items become weak and do not last long and even wooden items get spoilt fast.
