It represents the interrelationships between different plants and animals. The energy is derived from the sun and converted into stored energy by plants through photosynthesis, which travels up the food chain.

A food chain is a diagram used by biologists to better understand ecosystems. It represents the interrelationships between different plants and animals. The energy is derived from the sun and converted into stored energy by plants through photosynthesis, which travels up the food chain. The energy returns to the ecosystem after the organisms die and decompose back into the Earth. This process is an endless cycle.
In food chains, living organisms are grouped into categories called producers and consumers, which come in multiple tiers. For example, secondary consumers feed on primary consumers, while tertiary consumers feed on secondary consumers. Apex predators are the animals at the top of the food chain. They are the highest category consumer in an ecosystem, and apex predators do not have natural predators.
