Color the pictures, then cut and string them to make a mobile. No matter what you had to eat this morning, sunlight made it all possible. Only plants can use sunlight in this way. While animals can't use sunlight to make food, they do get energy from the sun each time they eat plants, or eat other animals that feed upon plants. This transfer of food from plants through a series of animals is known as a food chain.
Food chains exist everywhere - even in the cave.
They all have one thing in common - sunlight. Sometimes bits of dead leaves or other plants are carried into the cave by rainwater. This organic matter continues to decompose with the aid of bacteria and fungi present in the cave. Animals, such as crickets and bats, add to this organic material through their droppings. All of this makes food for small cave dwelling animals such as amphipods, isopods, and beetles.
