Detailed explanation-1: -In food webs, arrows point from an organism that is eaten to the organism that eats it. As the food web above shows, some species can eat organisms from more than one trophic level.

Detailed explanation-2: -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-3: -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-4: -Arrows on a food chain, or food web, represent the flow of energy. The placement of the arrows in a food chain or food web is very important. The arrows always show the direction of the energy as it is transferred from one organism to another. The flow of energy can also be represented within an energy pyramid.

Detailed explanation-5: -A food chain is defined as the linear sequence of transfer of matter and energy in the form of food from one organism to another in an ecosystem.
