Vedclass · Answer

(A) The correct matches are as follows:$1.$ Mycorrhiza: These are symbiotic associations between fungi and roots of higher plants. They help in the absorption of phosphorus from the soil $(1-b)$.$2.$ Nostoc: These are cyanobacteria that act as autotrophic $N_2$-fixers $(2-d)$.$3.$ Azospirillum: These are bacteria that live in the soil and act as free-living $N_2$-fixers $(3-a)$.$4.$ Rhizobium: These bacteria form symbiotic associations with the root nodules of leguminous plants to fix nitrogen $(4-c)$.Therefore, the correct sequence is $1-b, 2-d, 3-a, 4-c$.
