Detailed explanation-1: -Expert-Verified Answer. The energy organisms need to live and grow first enters the ecosystem when Plants take in light energy from the sun. These energy and nutrients from plants are passed around through the food chain, when one organism eats another organism.
Detailed explanation-2: -Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
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.
Detailed explanation-4: -A food chain describes how energy and nutrients move through an ecosystem. At the basic level there are plants that produce the energy, then it moves up to higher-level organisms like herbivores. After that when carnivores eat the herbivores, energy is transferred from one to the other.
Detailed explanation-5: -The energy flow is the amount of energy that moves along the food chain. This energy flow is also known as calorific flow.
