Detailed explanation-1: -The arrows on a food chain indicate where energy is being passed. For example, an arrow pointing from some grass to a zebra means the grass gives energy to the zebra (when the zebra eats the grass). The arrows on a food chain indicate where energy is being passed.It also specifies the direction of the flow of energy.

Detailed explanation-2: -Arrows are used to show the feeding relationship between the animals. The arrow points from the organism being eaten to the organism that eats it. For example, an arrow from a plant to a grasshopper shows that the grasshopper eats the leaves. Energy and nutrients are moving from the plant to the grasshopper.

Detailed explanation-3: -The arrow always points to the higher trophic level, that is from the prey to the predator and this indicates the flow of energy in the form of food. Energy from one trophic level to another is not completely transferred.

Detailed explanation-4: -Explanation: For that reason, we can say that the arrows represent the flow or transfer of energy in an ecosystem. It also specifies the direction of the flow of energy.
