GC 101 Chapter 5 – Flashcards

. A biome is described by A. A specified bioregion B. Broadly similar environmental conditions C. A watershed divide, generally D. Geographic location E. Large landforms in the area

. Location of specific biomes can be predicted based on A. The Coriolis Effect B. The 2nd Law of Thermodynamics C. Precipitation and temperature D. Seasonal variations in sunspots E. Large landforms in the area

Cloud forests are found in ________ areas in tropical regions. A. Hot coastal B. Cool mountainous C. Cool plains D. Low elevation E. Valley

. Neo finds himself sweating in a moist forest but there aren't many streams or wetlands. He is amazed by the tremendous amount of biodiversity including an abundance of biting mosquitoes. Has he inadvertently gotten closer to his goal of finding a boreal forest? A. Yes B. No - the description is that of a tropical seasonal forest C. No - the description is that of a temperate deciduous forest D. No - the description is that of a tropical rainforest E. No - the description is that of a temperate rainforest

A biome absent from North America is the A. Temperate deciduous forest B. Alpine tundra C. Desert D. Tropical rainforest E. Temperate rainforest

Which of the following is an example of a specialization that plants in the desert may have? A. Storing water in stems or roots B. Reducing water loss with thick epidermal layers C. Salt tolerance D. Storing water in stems or roots and reducing water loss with thick epidermal layers E. All of these are adaptations of plants living in desert conditions

Humid tropical forests have extraordinary biological diversity A. Because of the very fertile tropical soils B. Because rainfall dissolves soil nutrients and makes them available to plants C. Because water is not a limiting factor D. Despite a complete absence of nutrients in the environment E. Despite the poor, weathered soils

Tropical seasonal forests are specially adapted to tolerate A. Annual cycles of extreme heat and extreme cold B. Years of drought followed by years of rain C. Annual cycles of severe drought and heavy rain D. Extreme drought and cold at the same time E. Extreme heat

You are in an area that is relatively hot. You bend down and notice that there are tracks in the soil that are very old. Since you know that this area is easily destroyed by human activity and the harsh climate slows recovery from human damage you conclude that this biome is A. A tropical dry forest B. A desert C. Tundra D. A grassland E. A wetland

Morpheus, Trinity and Neo are on the wet western coast of North America and as they look around they see lots of mosses, lichens and ferns covering the tree branches. Condensation from fog on the leaves is a major form of precipitation. Where are they? A. Temperate rainforest B. Boreal forest C. Tropical rainforest D. Southern pine forest E. Tropical savannah

. Deciduous forests A. Are adapted to extremely cold climates B. Have trees that bear seeds in cones C. Have trees that shed their leaves seasonally D. Are not useful commercially E. Are not found in the African co

Many people in the United States take trips in the spring to see annual flowers that grow and flower before they are shaded by canopy. Where are these people going? A. Deserts after winter rain showers B. Prairies or grasslands C. Tropical rainforests D. Temperate deciduous forests E. Boreal forests

Boreal forests are generally A. Cold and dry, with extensive barren areas B. Warm and humid, with large rivers C. Dry because water is frozen most of the year D. Slow-growing because of the cold temperatures E. Soggy in the summer because of permafrost

Morpheus has been led into a wilderness environment and left to fend for himself for the summer. Luckily, he has a good coat because it looks like there may be a frost during the night and the mosquitoes are everywhere. As he looks around, he is relieved because he recognizes some of the plants. There are some mosses, lichens, small shrubs, sedges and grasses. Which biome is he in? A. Tropical rainforest B. Wetland C. Temperate rainforest D. Tundra E. Coastal area

57. The biome type that has a short growing season and is summer feeding and breeding grounds for caribou and musk-ox is the A. Temperate grasslands B. Bog or fen C. Boreal forests D. Arctic tundra E. Arctic deserts

Mangrove trees are found along ________________ shorelines. A. Tropical freshwater B. Tropical saltwater C. Temperate freshwater D. Temperate saltwater E. Tropical and temperate saltwater

Which of the following protects mainland shores form the force of waves? A. Wetlands B. Barrier islands C. Coral islands D. Estuaries E. Volcanic islands

60. Freshwater ecosystems A. Lack oxygen B. Lack carbon dioxide C. Include lakes, marshes, bogs and fens D. Do not contain thermoclines E. Are not affected by nutrient availability

The thermocline is the layer in a lake at which A. Pollutants are trapped and held B. Seasonal lake mixing occurs C. The warm upper zone meets the cold lower zone D. Nutrient levels are the lowest E. Light no longer penetrates enough for photosynthesis to occur

Wetlands are biomes that A. Are wet all year round B. Are wet at least some of the year C. Have fresh, not salty, water D. Receive more rainfall than other ecosystems E. Have salty, not fresh water

The biome type that has lost the greatest percentage of its original area due to human activities is the . Temperate conifer forest B. Tropical rainforest C. Temperate deciduous forest D. Temperate grassland E. Tropical grassland

. Estuaries are noted by biologists because they have few, but highly specialized, biological niches. True False

Wetlands perform a major ecosystem service of trapping and filtering water as it passes through the wetland area. True False

Arctic deserts and tundra are the least disturbed by humans since they are usually unattractive places for humans to live.
