Overview

Earth's biosphere supports several unique biomes and ecosystems. Though they operate as self-contained units, these regions also operate as part of a global network, nurturing interdependence among greatly diverse plant and animal species. The evolution of these wondrous realms-both aquatic and terrestrial-and the various natural elements that distinguish them from one another are the subjects of this comprehensive volume.
