Aquatic Food Chain Explained: From Phytoplankton to Top Predators #3640864 (License: Personal Use)

This diagram depicts a classic marine trophic cascade: photosynthetic phytoplankton form the base, consumed by zooplankton, which are then preyed upon by small fish, ultimately supporting large predatory fish like sharks. Each arrow signifies energy transfer, with significant loss at each trophic level due to metabolic demands and inefficiency.
