Explanation:

The tundra biome is characterized by a lack of trees and has permafrost, which is permanently - frozen soil. Savannas have grasses and scattered trees. Pelagic refers to the open ocean.

Deciduous forests have trees that shed their leaves seasonally. Deserts are dry regions. The littoral zone is near the shore of a body of water. Biochemical oxygen demand is related to water quality. Phytoplankton are free - floating photosynthetic organisms. Boreal forests have coniferous trees. Grasslands have grasses as the dominant vegetation. Euphotic refers to the well - lit upper layer of a body of water. Benthic refers to the bottom of a body of water.
