Any organism that lives in an oxygen-rich environment generally depends on aerobic respiration since it provides maximum energy.

Examples

• Humans and animals: For daily energy, movement, and organ function
• Plants: Use it in mitochondria to release energy from glucose, especially at night
• Fungi: Like molds and mushrooms, which rely on oxygen for growth
• Aerobic bacteria: Found in soil, water, and inside living organisms, contributing to ecological balance

Aerobic respiration is almost universal among complex life forms.
