Question

a novel fungus was introduced into a forest, causing disease and death to the trees that the fungus was living on. what type of symbiotic relationship is described here? a mutualism b commensalism c parasitism

Explanation:

Mutualism is a relationship where both organisms benefit. Commensalism is when one benefits and the other is neither helped nor harmed. Parasitism is when one organism (the parasite) benefits at the expense of the other (the host), often causing harm like disease or death. Here, the fungus (parasite) causes disease and death to the trees (host), which fits parasitism.

Answer:

C. Parasitism
