Shows what eats what and consists of many food chains in an ecosystem

Detailed explanation-1: -A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.
Detailed explanation-2: -A food chain is a series of steps in which organisms transfer energy by eating and being eaten. Food chains can vary in length.
Detailed explanation-3: -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-4: -A food chain refers to the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism. The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain.
