Answer 2

1. The biotic factor which spoils the food item is D) bacteria

• Bacteria are microscopic organisms that spoil food by breaking it down to create unwanted products. This is accompanied by a foul odour, shabby appearance, change in texture and a bad taste.
• The food spoilage is mainly done by the bacteria Pseudomonas marginalis.
• To break down the food, bacteria require hot and humid conditions. This is the reason why perishable food items should be kept in the deep freeze.
