Algebraic transformation of the exponential correlation into an expression based on the decadic logarithm yields the law of Beer–Lambert:

where [d] = 1cm, [c] = 1moldm-3, and [e] = 1dm3mol-1 cm1. e is the molar absorption   coefficient.

where [d] = 1cm, [c] = 1moldm-3, and [e] = 1dm3mol-1 cm1. e is the molar absorption coefficient.

Communities may be identified and recognized by several features that may be quantitative and qualitative.

Quantitative characters are those that can be measured, e.g., density, abundance, frequency, cover area and basal area of species present in a given area.

COMMUNITY ZONATION - One of the most noticeable features of communities is that the species composition of the community changes as one moves across the landscape. 

With the change in environmental conditions, some species become better able to survive and compete.
