Detailed explanation-1: -Energy flow is the flow of energy through living things within an ecosystem. All living organisms can be organized into producers and consumers, and those producers and consumers can further be organized into a food chain. Each of the levels within the food chain is a trophic level.

Detailed explanation-2: -The energy flow is the amount of energy that moves along the food chain. This energy flow is also known as calorific flow.

Detailed explanation-3: -In general, energy flows from the Sun to producers and then to consumers. The path is linear as the energy present in one step is transferred to the next. You can find specific examples of this pathway in an ecosystem. For example, suppose you observed a grassland ecosystem.
