Food Chain Diagram (4 Links) — free printable diagram

About this illustration

This educational image depicts a simple marine food chain, illustrating the flow of energy from producers to apex predators. It visually presents phytoplankton (magnified in a circle) at the base, followed by krill, then a fish, and finally a seal, each connected by a downward arrow. The image teaches fundamental concepts of ecosystems, trophic levels, and predator-prey relationships in a marine environment. This clear, flat-style illustration is ideal for science worksheets, educational slides, or as a visual reference for discussing food chains in K-12 biology and environmental science lessons.
