Biodiversity: The variety of the plant and animal life in the world or in one particular habitat, a high level of which is considered important of desirable.
Biomes: A large naturally occurring community of forests or fauna occupying a major habitat.
Climate: The weather conditions prevailing in an area in general or over a long period.
Latitude: The angular distance of a place north or south of the equator.
Biomass: Weight of living material. - 2Types 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. - 3Tropical 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. - 4Coniferous Forest: Occurs in high latitudes and stretches as a belt across North America+Eurasia. Leaves of the trees are needle like to withstand the cold and loss of moisture. Deciduous Forest: Low winter temperature. Trees shed leaves. 3 main areas- North America, Europe, East Asia.Mediterranean
