What is the primary mechanism that allows animals to digest food and absorb nutrients without damaging their own body tissues?

  • A: Rapid metabolism of food.
  • B: Specialized enzymes that only target food.
  • C: Compartmentalized processing within a tube-like system.
  • D: Exclusively alkaline environments for digestion.

Explanation

The text explicitly states, "An animal digests food using compartmentalized processing in a tube-like system. Compartmentalization protects body tissues while allowing enzymes and acids to break down nutrients." This clearly identifies compartmentalized processing as the primary mechanism for preventing self-digestion.
