The photic and aphotic zones in the ocean differ in light penetration, affecting the types of organisms present. Light decreases as one goes deeper, impacting the distribution of marine life. The photic zone supports more diverse life forms due to sunlight availability.
Photic Zone: It is the upper layer of a body of water where there is sufficient sunlight for photosynthesis to occur, supporting a wide variety of marine life.
Aphotic Zone: This is the deeper, darker layer of the ocean where sunlight cannot penetrate, resulting in a lack of photosynthesis and a different set of adapted organisms.
Organisms: Going down in a submarine, one would see decreasing light levels and fewer plants but increased bioluminescent organisms. The most life forms are typically found in the photic zone due to the availability of sunlight supporting diverse marine life.
