Producers must be at the base of every food chain because they get their energy from the sun, and then they give their energy to the consumers. The reason why it is like this because the producers just produce energy but don't eat other organisms to get their energy. That is why the producers must be at the bottom of every food chain.
I hope this helps.

A predator is an organism that hunts, kills, and consumes other organisms (prey) for food. They play a key role in regulating the populations of other species in an ecosystem.
A predator in the food chain is an Eagle because they pick up almost anything to feed young and its self.

A Komodo dragon is a predator at the top of its food chain, so it is not considered a food chain in itself. A food chain is a linear flow of energy from one organism to another, showing the transfer of nutrients through various levels of a community. The Komodo dragon would be a part of a food chain as a predator preying on various lower-level organisms for its food.
The last thing on a food chain is called the top predator or apex predator. This is the organism that is at the highest trophic level and typically has no natural predators of its own.
A basic food chain starts with a primary producer and has a chain of primary, secondary, and tertiary predators. This would start with algae as the primary producer, minnows as the primary predator, sunfish as the secondary predator and pike as the tertiary predator.
A food chain can have as few as three links. For example, a plant being eaten by a herbivore, which is then eaten by a predator.
The final step in the food chain is typically the top predator, such as apex predators like lions, sharks, or eagles. They are at the top of the food chain because they have no natural predators themselves.
