Frequently Asked Questions
Why is the study of life processes important for understanding living organisms?
Life processes are fundamental to understanding how organisms grow, reproduce, maintain homeostasis, and respond to environmental changes.
How does photosynthesis differ from respiration?
Photosynthesis uses light energy to produce glucose from CO2 and water, while respiration breaks down glucose to release energy.
