Detailed explanation-1: -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-2: -The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants. A small proportion of this chemical energy is transformed directly into heat when compounds are broken down during respiration in plants.

Detailed explanation-3: -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.
