Vertical distribution of different species occupying different levels in a biotic community is known as

Vertical distribution of different species occupying different levels in a biotic community is known as stratification.

Zonation, defined as biological distribution pattern along the vertical dimension in an aquatic habitat, is the most obvious biological phenomenon in the intertidal zone throughout the shore globally.

Pyramid is used to represent the food or energy relationship between organisms at different trophic levels. Even age distribution and sex ratio in a population is represented by pyramid.

Ecological speciation occurs when reproductive isolation evolves as a byproduct of adaptive divergence between populations.
