Match the columns:

Column-$I$	Column-$II$
$(i)$ Primary succession	$(i)$ Development of ecosystem
$(ii)$ Ecological succession	$(ii)$ Lichens
$(iii)$ Pioneer species on rocks	$(iii)$ Near to the equilibrium with the environment
$(iv)$ Climax community	$(iv)$ New species on bare environment

(D) The correct matching is as follows:
$(i)$ Primary succession occurs on bare areas where no life existed previously,involving new species on a bare environment $(iv)$.
$(ii)$ Ecological succession is the gradual and predictable change in the species composition of a given area,leading to the development of an ecosystem $(i)$.
$(iii)$ Pioneer species on rocks are the first organisms to colonize a bare area,which are typically lichens $(ii)$.
$(iv)$ Climax community is the final stable community in a succession that is near to the equilibrium with the environment $(iii)$.
Therefore,the correct sequence is $(i-iv, ii-i, iii-ii, iv-iii)$.
