Breaking down of large molecule is necessary to convert large molecules into small easily digestible molecules so that the food energy stored in them can be stored in some other form specifically chemical energy and can be used at later stages. However, in the process of conversion of large molecules into small molecules , a certain amount of heat energy is used.

Hence, option C is correct

External ear structure that helps to localize the direction from which sound arises

Step2247 [10]

The external ear structure is called the Pinna.

The Pinna helps to channel sound waves into the ear.

I have attached an image of a dog's ear to show you the external structure called the Pinna.

I hope this helps! I'm happy to answer any other questions you might have :)
