Explanation

All four statements about mushrooms are correct, highlighting their diverse roles in ecology and human use. Medicinal properties are attributed to various species, such as Penicillium from which penicillin is derived. Psychoactive properties are found in mushrooms like Psilocybe, while insecticidal properties are observed in species like the biocontrol agent Metarhizium.
