Description:
This quiz is based on Respiration in Organisms. Respiration is the process by which living organisms break down food to release energy required for growth, movement, repair, and other life activities. Most organisms use oxygen for respiration and release carbon dioxide.
Respiration may be aerobic (with oxygen) or anaerobic (without oxygen). Different organisms have different respiratory organs such as lungs in humans, gills in fish, tracheae in insects, and skin in earthworms.
