The statement that all food chains begin with a plant is true because
they start with plants as plants are the only producers (can make their own food) and the whole food chain depends on them.
Without plants, there would be no primary consumers and that would mean no food for the secondary consumers and so on, disturbing the entire food chain!
They start with plants because energy comes from the sun and plants are the only ones who can make food with that energy.
