ES101 Lecture Notes - Lecture 13: Stoma, Cactus, Evaporation
Document Summary
Biomes: distribution location and extent, general characteristics climate, plant and animal types. Adaptations: human impacts changes, resilience, chapter 6: 6-3 to 6-7, broad categories of ecosystems. Vegetation is typically how we identify biomes: main categories. Mountain strong geologic feature as the elevation of the mountain changes its vegetation, wildlife, etc. The major difference between grasslands and forests is precipitation. For example, in the us there is a lot of precipitation on the west coast that dries up when it gets to the mountains, leading to a grassland after the mountains. Temperate low moisture, interiors: mountains. High elevation rapid temperature change, variable precipitation. Deserts: evaporation > precipitation, tropical sub tropical. Adaptations: small leaves, deep roots and shallow roots, store biomass in seeds, wax on leaves, store water in leaves plants perspire, hair on leaves. Evaporate from mouth, large ears, dark colours: retain water. Burrowing, food sources, slid wastes: acquire water. Plants (cacti), recycle water, retain moisture from air.
