3. What is the primary drying mechanisms?Evaporation (sun/wind drying) and sublimation (freeze-drying)
4. What is dried fish and why does it last so long?Dried fish has most of its water removed, so germs and bacteria can't grow. This keeps it safe to eat for months or even years.
5. How do people dry fish?People use the sun, wind, or smoke to pull water out of the fish. In hot, breezy places, the fish dries quickly.

Water Activity (a_w): A measure of the unbound water available in a food product for microbial growth and chemical reactions.
Sublimation: The direct phase transition of a substance from solid to gas, bypassing the liquid phase, as utilized in freeze-drying.
Enzymatic Degradation: The breakdown of food components by naturally occurring enzymes within the food itself, leading to spoilage.
