When two organisms interact with each other in order to survive it is known as a symbiotic relationship. Both the organisms living in a symbiotic relationship gain equal benefits. Mutualism, competition, parasitism , and commensalism are four main types of symbiotic relationships. When two species choose to live together it is known as facultative symbiosis and when two species live together in order to survive it is known as obligate symbiosis.

Question

Fungal hyphae form a mesh of tissue that infiltrates food sources and absorbs nutrients. This tissue structure is called __________ . A. Mycelium B. Fungal roots C. Gametangia D. Zygospores E. None of these

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host.
