Discover the wonders of Mulu’s dense forest is home to the famed pinnacles and a variety of known and yet-to-be-discovered flora and fauna. Its ecosystems are a complex web of organisms, which include plants, animals, and fungi, that rely on each other to survive. The forest floor is dark and busy, full of decomposing debris from organic matters that fall from above and thriving with worms, bugs, beetles, and weevils. These organisms are decomposers that break down the decaying materials, turning them into nutrients that are then absorbed by the shallow roots of the rainforest trees. Dozens of predators later feed on these decomposers.
