Vedclass · Answer

(D) The correct matches are as follows:$(1)$ Mycorrhiza: These are symbiotic associations of fungi with roots of higher plants,which help in the absorption of phosphorus from the soil. Thus,$(1-Q)$.$(2)$ Nostoc: These are cyanobacteria that act as autotrophic $N_2$-fixers. Thus,$(2-S)$.$(3)$ Azospirillum: These are bacteria that live in the soil and act as free-living $N_2$-fixers. Thus,$(3-P)$.$(4)$ Rhizobium: These bacteria form symbiotic associations with the roots of leguminous plants to fix nitrogen. Thus,$(4-R)$.Therefore,the correct sequence is $(1-Q), (2-S), (3-P), (4-R)$.

Column $X$	Column $Y$
$(1)$ Mycorrhiza	$(P)$ Free-living $N_2$-fixer
$(2)$ Nostoc	$(Q)$ Phosphorus absorption
$(3)$ Azospirillum	$(R)$ Leguminous plants
$(4)$ Rhizobium	$(S)$ Autotrophic $N_2$-fixer
