🌿 Food Chain / Food Web Builder
Drag organisms from the library to build food chains and food webs. Connect them to show who eats who. Download your creation!
Class 3–8 · Biology / Ecology
Start Building Your Food Web
Click any organism in the library to add it here, or load an example chain.
🌱 Start with Producers (plants)
🐾 Add Consumers (animals)
🔗 Use Connect to draw arrows
⬇️ Download your food web as a PNG
📚 How to Use
- Add organisms — click any organism card in the library panel to place it on the canvas.
- Move organisms — drag any organism card to reposition it on the canvas.
- Connect organisms — click Connect Organisms, then click the prey first, then the predator. The arrow shows energy flow (from prey → predator).
- Delete a connection — hover over an arrow and click the red × button.
- Download — save your food web as a PNG image with the Ocoviz watermark.
🌿 Food Chain Science Notes
Energy Flow
Energy flows one way through a food chain: Sun → Producers → Consumers. Only about 10% of energy transfers to the next level.
Trophic Levels
Each step is called a trophic level. Level 1 = Producers. Level 2 = Primary consumers. Level 3 = Secondary consumers, and so on.
Food Web vs Chain
A food chain is a single path. A food web shows all the interconnected chains in an ecosystem — more realistic!
Decomposers' Role
Decomposers break down dead organisms, returning nutrients to the soil. Without them, ecosystems would be buried in dead matter.
