• D. A-2, B-1, C-3, D-4

Answer 1

The correct option is A A-2, B-3, C-4, D-1

Saprophytes are organisms that derive their nutrition from dead or decaying organic matter. Rhizopus, Aspergillus and mushrooms are some of the examples of saprophytes.

In parasitism, only one species benefits (parasite) and the interaction is harmful to the other species (host).
e.g: human liver fluke, malarial parasites such as P. vivax, P. falciparum, etc.

Lichens is the mutualistic relationship between a fungus and cyanobacteria. Similarly, mycorrhizae is the symbiotic association between fungi and the roots of higher plants.
