(D) During ecological succession,the community undergoes a series of sequential changes known as seral stages until it reaches a stable climax community.$1$. $I.$ Changes in species diversity occur as pioneer species are replaced by more complex organisms.$2$. $II.$ There is a gradual increase in the number of species and the total number of organisms as the habitat becomes more favorable.$3$. $III.$ As the community matures,the total biomass increases significantly due to the accumulation of organic matter and the development of complex vegetation structures.Therefore,all three statements are correct.

$(a)$ Fourth trophic level	$(i)$ Crow
$(b)$ Second trophic level	$(ii)$ Vulture
$(c)$ First trophic level	$(iii)$ Rabbit

The changes that occur in successive seral stages to reach a climax community are:
