Types of Ecosystems: Temperate Grassland: Grasses dominate because climate is unsuitable for the growth of trees + shrubs. Occurs in dry continental interiors of North America. Mountains: Occurs in high mountains. Climate is similar to tundra. Very cold due to decrease in altitude. SNOW.
Tropical Forest: Warm+Humid. Close to equator. High temperature and rainfall. Vegetation grows quickly. Savannah: Found along the equator. Climate is dry. Primary productivity is low. Tall trees and scattered bushes. Extensive in Africa. Desert: Lack of vegetation due to lack of rainfall. Extends over a wide range of latitudes. Biome experiences a range of different temperatures. Tundra. Long+Cold winters. Strong winds and little precipitation. Vegetation is typically stunted+grow close to the ground. Grasses,mosses+lichen.
