Answer 2

We can say that the food has got spoilt in the following way.

Explanation:

• Spoiling of food reduces the nutritional value of the food.
• Food spoilage is caused by the growth of micro-organisms like bacteria and yeast in the food.
• These organisms utilise the nutrients from the food and produce waste products.
• The waste products include various acids.
• These acids oxidise the nutritious food components and generates certain by-products which impart a foul odour to the rotten food.
