Basics of Ecology: Terrestrial Biomes: Deserts, Grasslands, and Forests DVD

Students first are introduced to the 4 requirements of life: nutrients, energy, liquid water, and temperatures appropriate for carrying out life processes. The program then defines the factors that affect climate, such as latitude, proximity to oceans, and elevation. The relationship of climate to the type of vegetation found in a biome is explained before the program introduces the major terrestrial biomes: tropical, temperate, and deciduous rainforests; savannas; grasslands; chaparrals; taiga; tundra; and deserts. 2005.
