A food chain shows how each living thing gets food, and how nutrients and energy are passed from creature to creature. Food chains begin with plant-life, and end with animal-life. Some animals eat plants, some animals eat other animals. A simple food chain could start with grass, which is eaten by rabbits.
In the question above, grasshopppers eat grass, toads eat grasshoppers, snakes east toad and hawks eat snakes.
