Why does bread mould grow profusely on a moist slice of bread rather than on a dry slice of bread?

(N/A) Moisture is an essential factor for the growth of fungal hyphae. $A$ moist slice of bread provides both the necessary moisture and nutrients required for the bread mould to thrive. In contrast,a dry slice of bread provides nutrients but lacks the moisture needed for the spores to germinate and the hyphae to grow,thus preventing the mould from growing.
