Answer 2

In the Summer season, the temperature is very high. The high temperature promotes the growth of the microorganisms (bacteria) which utilizes the sugar in the milk as the source of energy. Hence we need to boil milk four to five times in summer.

Explanation:

• The season that falls between the spring and autumn is called summer. Summer is the hot season.

• Milk is the complete food which is the source of all nutrients.

• It contains the carbohydrate called lactose.

• It gives favorable condition for the growth of microorganisms. Lactobacilli is the predominant microbe present in milk.

• It converts the lactose into lactic acid through fermentation process.

• This lactic acid-producing bacteria and other microbes grow rapidly in the hot and humid climate than in the normal temperature.

• Boiling at high temperature up to 100°C will kill the death of those bacteria present in the milk.
