bats hanging close together inside a cave
More than 15 million Mexican free-tailed bats live in Bracken Cave in Texas. Every night at sunset, the bats leave the cave to find food. They eat flying insects such as moths, flies, and wasps.
When so many bats live together in one cave, they produce a lot of bat feces, or guano. The guano builds up on the cave floor and provides food for fungus and bacteria. The fungus and bacteria are eaten by millipedes and other small crawling insects. These small insects are eaten by larger organisms, such as centipedes, spiders, and salamanders.
