Aerobic respiration is essential because it provides the main supply of ATP, which is needed for survival. Every cell activity - from muscle movement to brain function - depends on this energy.

Importance

• Provides energy for daily body functions
• Maintains organ systems like heart, lungs, and brain
• Supports growth, repair, and immunity
• Helps organisms adapt to stress and environmental changes

Without aerobic respiration, complex life like humans, animals, and plants could not exist.
