Scene 2

Terrestrial Ecosystems	: Terrestrial ecosystems are exclusively land-based ecosystems. There are different types of terrestrial ecosystems distributed around various geological zones. Forest Ecosystem A forest ecosystem consists of several plants, animals and microorganisms that live in coordination with the abiotic factors of the environment. Grassland Ecosystem In a grassland ecosystem, the vegetation is dominated by grasses and herbs. Temperate grasslands, savanna grasslands are some of the examples of grassland ecosystems. Tundra Ecosystem Tundra ecosystems are devoid of trees and are found in cold climates or where rainfall is scarce. These are covered with snow for most of the year. The ecosystem in the Arctic or mountain tops is tundra type. Desert Ecosystem Deserts are found throughout the world. These are regions with very little rainfall. The days are hot and the nights are cold..

Aquatic Ecosystem : Aq uatic ecosystem are ecosystems present in a body of water . Freshwater Ecosystem The freshwater ecosystem is an aquatic ecosystem that includes lakes, ponds, rivers, streams and wetlands. These have no salt content in contrast with the marine ecosystem. Marine Ecosystem The marine ecosystem includes seas and oceans. These have a more substantial salt content and greater biodiversity in comparison to the freshwater ecosystem..
