- Mechanical digestion — food is physically broken into smaller parts. For instance, by chewing.
- Chemical digestion — food is broken down by acids and enzymes into its basic units.

Why do animals need a digestive system?
Digestion is the process in which complex substances are broken down to simpler substances and energy is produced. It is a vital process for an animal’s survival because of this process the energy present in the food is made available to the cells in our body and due to that energy, we can work.
What animal has no digestive system?
There’s no sac in the middle that secrete powerful acids and digestive enzymes. In other words, the platypus has no stomach. The stomach, defined as an acid-producing part of the gut, first evolved around 450 million years ago, and it’s unique to back-boned animals (vertebrates).
