<span>B- tree > insect > frog> snake> hawk
The food chains are represented by organisms interconnected by red arrows that point in the direction of the one that's eating. So, the relation that is explicit by the arrow is that the organism from where the arrow departs is eaten by the organism where the arrow is pointing towards to.
