<h3>What is life zone concept?</h3>
- C. Hart Merriam created the term "life zone" in 1889 to refer to regions with comparable plant and animal groups. Depending on height, location, and latitude, the climate and ecology of many places on the planet naturally divide into life zones.
- Altitudinal zonation is the term for the generally substantial dependence on elevation: the average temperature of an area falls as the height increases.
