What is meant by extracellular digestion? How is it different from intracellular digestion?

Explanation

### Step-by-Step Solution:

1. **Definition of Extracellular Digestion**:
- Extracellular digestion refers to the process of breaking down food outside the cells. In this process, digestive enzymes are secreted into a digestive cavity or environment, where they break down complex food substances into simpler molecules. These simpler molecules are then absorbed into the body through diffusion.

2. **Definition of Intracellular Digestion**:
- Intracellular digestion, on the other hand, occurs within the cells. In this process, food particles are engulfed by the cell through a process called phagocytosis, and then they are digested inside specialized compartments called lysosomes.
