Answer 1

food items such as the mango, lime, olive and many others are spoiled by the action of bacteria and fungi. to prevent this, we often make pickle. here, when the food is kept int he mixture of salt and oil, the concentration of the solution is very much higher than the of the bacterial of fungal cell. this solution (hypersonic solution) results in the shrinking or rupturing of the bacterial cell saving the food from its effect.

Answer 2

Food items that are generally spoiled by the presence of bacteria are fruits, vegetables, pickle, cooked rice etc. The microbes usually attack food items that we get from nature.

EXPLANATION:

Spoilage of food is the process in which the food that humans eat is deteriorated in such a manner that it does not remain edible. Bacteria may cause spoilage of food because when bacteria breaks down food, acids and waste products may be created which result in spoiling the food.

Cooked rice for instance is attacked by bacteria and becomes inedible. Rice can be prevented from spoilage by heating and boiling the cooked rice regularly.
