This is the study of how organisms are distributed across the planet in both space
(location) and time. it tells us about the history of organisms and the history of the
surface of the earth (as plates moved and shifted on it's surface.)

Biogeography.

Explanation:

In biology, some specific sections don't deal with various topics; they deal with any specific one. Biogeography is like these branches.  It deals specifically with the appearance of a species in any geographic area. Without this, it also includes the ecosystems in that geographic space within a noticeable geological time.

There are lots of species on the earth, but they don't live in the same place. They are distributed over the whole planet. Some species are found in soil, some are found in water. Along with this, some species are found in the polar region.

Biogeography mainly deals with this distribution of the species and ecosystem of any specific geographic area. This helps to understand the relationship between a species and the ecosystem of that place where it lives.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
