Food Web Diagram: Understanding Ecosystem Trophic Levels and Energy Flow #92256 (License: Personal Use)

This educational diagram maps a terrestrial ecosystem’s trophic structure: producers (apple tree, radishes, grass) support primary consumers (deer, mouse, grasshopper); secondary consumers (badger, snake, cardinal) feed on them; and tertiary consumers (cougar, eagle) sit at the top. Detritivores (earthworms, beetles) decompose organic matter, closing the nutrient cycle.

Used in biology classrooms, ecology websites, and science textbooks to teach energy transfer, food chains vs. webs, and ecosystem interdependence; matches user intent for learning or teaching ecological concepts.
