Explanation
In a food chain, energy is transferred from one trophic level to the next, with each level typically having fewer individual than the previous ones.In a food chain, producers have more energy than primary consumers. Producers are the first level in a food chain, and they produce their own food using energy from the sun. Primary consumers are the next level up in the food chain, and they eat the producers.
