Food Chain Diagrams: Ecosystem Energy Flow Explained #123916 (License: Personal Use)

Chain (a) depicts a classic terrestrial food web starting with trees and grasses feeding a deer, which is then preyed upon by a tiger. Chain (b) shows a wetland or grassland sequence: grasses → insect → frog → snake → eagle. Chain (c) represents an aquatic system: algae → scorpion → fish → heron. Arrows indicate the direction of energy transfer.

Used in educational science content (e.g., biology textbooks, ecology lesson plans, museum exhibits) to teach trophic levels and ecosystem dynamics; matches user intent for visual learning about food webs and biodiversity.
