To describe: The focus of the science of biogeography.

Answer to Problem 1LC
The distribution and the variations in the distribution of the different floral and faunal communities throughout the Earth’s landscape over geological time is defined by biogeography.
Explanation of Solution
Biogeography as the name itself suggest includes the combination of both biological and geographical elements. It is therefore described as the study of the distribution patterns of various living organisms on Earth throughout the geological time.
Biogeography also considers the reasons for the variations in the distribution patterns of organisms. The living organisms including the plants and the animals present on the Earth varies with time and space. Some may be adapted to some specific conditions only. Thus biogeography focusses on the generalization of the distribution patterns and studies their significance.
