Give a comparative account of the classes of Kingdom Fungi under the following:
$(i)$ Mode of nutrition
$(ii)$ Mode of reproduction

(N/A) Phycomycetes: Includes members like $Rhizopus$,$Albugo$,etc.
$(i)$ Mode of nutrition: They are obligate parasites on plants or saprophytes found on decaying matter.
$(ii)$ Mode of reproduction: Asexual reproduction occurs via motile zoospores or non-motile aplanospores produced endogenously in a sporangium. Sexual reproduction is isogamous,anisogamous,or oogamous,resulting in a thick-walled zygospore.
$(B)$ Ascomycetes: Includes members like $Penicillium$,$Aspergillus$,$Claviceps$,and $Neurospora$.
$(i)$ Mode of nutrition: They are saprophytic,decomposers,parasitic,or coprophilous (growing on dung).
$(ii)$ Mode of reproduction: Asexual reproduction occurs via exogenous spores called conidia. Sexual reproduction occurs via ascospores produced endogenously in sac-like asci,arranged within ascocarps.
$(C)$ Basidiomycetes: Includes members like $Ustilago$,$Agaricus$,and $Puccinia$.
$(i)$ Mode of nutrition: They grow as decomposers in soil or on logs and tree stumps,or as parasites causing diseases like rusts and smuts.
$(ii)$ Mode of reproduction: Asexual reproduction occurs commonly through fragmentation; asexual spores are absent. Sexual reproduction involves plasmogamy (fusion of two different strains of hyphae),forming a dikaryon that gives rise to a basidium,which produces four basidiospores.
$(D)$ Deuteromycetes: Includes members like $Alternaria$,$Trichoderma$,and $Colletotrichum$.
$(i)$ Mode of nutrition: They are saprophytes,parasites,or decomposers of leaf litter.
$(ii)$ Mode of reproduction: Asexual reproduction occurs only through conidia. Sexual reproduction is absent.
