In a food chain, the arrows show the direction of energy flow. They point from the organism being eaten to the organism that eats it, showing who gets energy from whom.

Simple example

If the chain is: grass → rabbit → fox the arrow from grass to rabbit means the rabbit eats the grass, and the arrow from rabbit to fox means the fox eats the rabbit.

Why it matters

The arrows help you read the food chain correctly and see how energy moves through an ecosystem. They do not just mean “is related to” or “is next to”; they specifically show transfer of energy and matter.

One-line answer

Arrows in a food chain represent the flow of energy from one organism to the next.
