In these food chains, arrows point from food to the organism that consumes it. Follow the arrow direction to identify a feeding link. A short chain is a model, not a complete ecosystem.

Worked example

Grass -> grasshopper -> frog means a grasshopper eats grass and a frog eats the grasshopper.

A food-chain model reads grass to grasshopper to frog. Each arrow points from the food organism to its consumer; this is a simplified chain, not a complete food web.
