Final answer:
Exposure to oxygen, exposure to sunlight, and deep fat frying are factors that can cause degradation of food.
Step-by-step explanation:
The factors that can cause degradation of food include exposure to oxygen, exposure to sunlight, and deep fat frying.
Exposure to oxygen can lead to oxidation of unsaturated fats, causing them to turn rancid. Sunlight can also contribute to the degradation of food, especially foods that are rich in fats. Deep fat frying involves subjecting the food to high temperatures, which can lead to the breakdown of nutrients and changes in food consistency.
