Step-by-step explanation:
Parasitic fungi live or colonize animals, plants, or other organisms on which they cause disease and even death or simply live at their expense.
Pseudogymnoascus destructans is a fungus known to cause white-nose syndrome (WNS), an infectious disease of bats. It is transmitted by direct contact between bats or with a contaminated environment. In fact, Pseudogymnoascus destructans invade and ingests the skin of hibernating bats, including their wings. This type of fungus is an ectoparasite. Ectoparasites are pathogens that generally infect only the superficial layers of the skin.
we can conclude that the correct answer is:
Answer:Parasitism
