Chapter 31: Self-Quiz Most plant species fit into only a few morphological types. Which type seems most restricted by temperature and rainfall? trees shrubs grasses perennial herbs annual weeds In which biome is the smallest fraction of carbon and nutrients present in the soil? tropical rain forest savanna tundra grassland coniferous forest How do mountain ranges create deserts? by lifting land up into colder, drier air by completely blocking the flow of air into desert areas, thus preventing clouds from getting there by forcing air to first rise and then fall, thus causing rain on one side of the mountains and desert on the other by causing the world wind patterns that make certain latitudes very dry by causing very steep slopes that are subject to erosion What is the primary reason that plants from distant, but climatically similar, places often look the same? common ancestry adaptation to the same physical conditions adaptation to similar herbivores continental drift effects of past climate change Which of these biomes has been increased in area by human activities? savanna temperate rain forest grassland coniferous forest desert What biome has the richest soil and has largely been converted to agriculture? tundra coniferous forest grassland tropical rain forest deciduous forest The earth is generally hotter at the equator because: The earth bulges out at the equator, making it closer to the sun. The natural curve of the earth places the equator nearer the sun. The sun shines over the equator more hours in the day. There are large oceans near the equator to absorb large amounts of heat. The sun's rays strike the earth at nearly a right angle at the equator. At 30 degrees north and south of the equator, there are very dry regions on the earth. Why ? Cool air falls, is warmed, and absorbs moisture. Warm air falls and absorbs moisture. Cool air rises and water condenses. Warm air rises and water is evaporated. Air flows laterally across the land from the temperate zone. A circular pattern of rotating water is called a ________. gyre cirque arete biome rotor Which of the following factors is (are) frequently limiting in terrestrial environments? water appropriate temperatures oxygen and nutrients nitrogen gas water and appropriate temperatures All of the following are(is) a characteristic of a tropical rain forest except: very high species diversity stratified vegetation fertile soil high temperatures arboreal animals A region with grasses as the dominant vegetation form, widely spaced trees and thorny shrubs, and a pronounced dry season is tropical deciduous forest savanna desert tundra chaparral Overgrazing and overuse of dry areas can cause them to receive even less rainfall, a process known as sahelization salinization dehydration laterization desertification Which of the following North American biomes has been almost completely destroyed and used for agriculture? desert temperate deciduous forest grassland tundra taiga The open water zone of a lake can be divided into the ________ and ________ zones. limnetic, littoral limnetic, profundal profundal, stratification temperate, taiga littoral, benthos Designed in cooperation with Andrew Stull and Steven Brunasso.
