- The food chain shows a linear sequence: Sun → Grass → Grasshopper → Bird → Hawk, with decomposers breaking down the hawk and returning nutrients to the grass.
- The food web illustrates multiple interconnected feeding relationships among various organisms, including producers (like algae, plants), consumers (like insects, fish, birds), and decomposers (bacteria, fungi).
- Energy flows from the sun to producers, then through primary, secondary, and tertiary consumers, with energy lost at each trophic level.
- Decomposers recycle nutrients back into the ecosystem, supporting plant growth and sustaining the food web.
- Unlike the simple food chain, the food web demonstrates ecosystem complexity, resilience, and interdependence among species.
