Final answer:
The Holdridge life classification scheme is a method of classifying and mapping ecosystems based on their climate and vegetation.
Step-by-step explanation:
The Holdridge life classification scheme is a method of classifying and mapping ecosystems based on their climate and vegetation. It was developed by American botanist Leslie Holdridge in 1947. The classification scheme takes into account temperature and rainfall to determine different life zones, such as rainforest, savannah, or desert. For example, an ecosystem with a high average annual temperature and high rainfall would be classified as a tropical rainforest.
