Fungi release enzymes which in turn help in digesting external material. Then the fungi absorb that digested compound that is created by the enzyme. For example, Cordyceps is a fungus that grow in the higher altitudes of the Himalayas and Tibetan plateau. It is a fungal parasite that infects ants and other insects like caterpillars . It uses the carcass of the insect as food, shooting out medusa-like stems that yield spores, ready to infect another host.
