Fungi make their food via absorption, and a large surface area makes nutrient absorption extremely efficient.
Breaking down of large macromolecules to monomers is known as catabolism. More the substance is broken down, larger its surface area gets. A particle with more surface area can be easily be metabolized by our body. Enzymes can act with full tendency on particles that have larger surface area and then an be easily digested and absorbed by out boy.

Well, your food is in your mouth, then it gets formed into a boli, which is a ball of food. Then the tongue pushes the boli down the esophogus where it starts to do a wave like motion called the peristalsis. Since it relies on the Digestive system, it is involuntary. So, the esophogus transfers the food down to the stomach, to the small intestine, to the large intestine, and finally down to the anus.
It's akin to vomit i.e. to bring up food in the stomach back to the mouth cavity or out of the body entirely. Whereas humans vomit to get rid of bad food, other animals regurgitate as part of normal digestion. For example, cows 'chew the cud'.
The structures inside the mouth, such as the tongue and the palate, help to manipulate and break down food into smaller pieces. The teeth also play a crucial role in physically increasing the surface area of food by chewing and grinding it into smaller particles, which makes it easier for enzymes to further break down the food during digestion.
Food is mechanically ground in the mouth by the teeth during the process of chewing. This initial mechanical breakdown of food helps to increase the surface area for enzymes to further break down the food during digestion.
They increase the surface area of small intestine and thus, increase the rate of absorption of food...
to increase surface area
Villi are finger-like projections in the small intestine that increase its surface area for better absorption of nutrients from food. They contain blood vessels and lymph vessels to transport nutrients to the rest of the body.
Food is broken down in the mouth by the chewing action. Different types of teeth are involved. Some teeth mash the food and some shred the food. Te purpose is to make the food pieces smaller and increase the amount of surface area of food that are exposed to saliva and stomach juices to speed the digestive process.

to increase surface area
To increase surface area of the food to enable digestion to function more effectively.
In the mouth, where digestion begins, food is reduced to smaller pieces by the teeth, increasing its surface area. The saliva begins the chemical break-down of the food and lubricates it for easier swallowing.
The ileum of a mammal has numerous finger-like projections called villi, which increase the surface area for absorption of nutrients. In addition, the epithelial cells lining the ileum have microvilli that further enhance absorption. The presence of specialized transport proteins in these cells enables the efficient uptake of digested food molecules.
The small hair-like projections are called villi. They are found in the small intestine and help increase the surface area for absorption of nutrients by providing a large area for contact with digested food.
