Ch.11 Sec.1 Biomes
Focus on California Earth Science 2008 Pearson Prentice Hall
| Question | Answer |
|---|---|
| What factors determine the type of biome found in an area? | temperature and precipitation |
| What are the six major biomes? | desert, rain forest, grassland, deciduous forest, boreal forest, and tundra |
| What biome has the most species? | rain forest |
| What do bison, wildebeests, antelopes, and kangaroos have in common? | they're grassy plain-dwelling large, grazing herbivores |
| True or false: deserts are always hot and dry | false (deserts have extreme temperature swings) |
| How is a saguaro (sawaro) cactus adapted to the desert? | its stem folds expand to absorb water in the rain, and then contract to keep water in |
| How are gila monsters adapted to the desert? | they can spend weeks at a time in their cool underground burrows |
| What's a common adaptation for animals in the desert? | greater activity at night during cooler temperatures |
| What do tree kangaroos and spider monkeys have in common? | they're consumers living in the rain forest canopy |
| What are the two types of rain forests? | tropical and temperate |
| How much rain a year do rain forests receive? | at least 200 cm |
| What is the floor of a rain forest like? | dark with few plants |
| What are the most abundant animals? | ants and termites |
| What adaptations do spider monkeys have for living in the rain forest canopy? | hands with thumbs and tails that can grasp onto branches |
| What adaptations do tree kangaroos have for living in the rain forest canopy? | long tails for balance; and feet with sharp claws and spongy pads that help with climbing |
| Why do trees not grow in grassland biomes? | insufficient rain |
| Which type of grassland usually receives more rainfall, prairie or savanna? | savanna |
| How much rain a year do deciduous forest biomes receive? | at least 50 cm |
| How long is the growing season in a deciduous forest biome? | 5-6 months |
| What are two methods by which wildlife in deciduous forest biomes survive the winter? | migration and hibernation |
| What are the two major differences between rain forests and deciduous forests? | quantity of rain and seasonal temperature variation |
| What's the Russian name for boreal forest? | taiga |
| What's a colloquial name for boreal forests? | sprucemoose forests |
| How are coniferous trees adapted to the cold climate of boreal forests? | thick, waxy needles that prevent water evaporation |
| How much precipitation does the tundra receive? | about as much as a desert |
| Why are there many shallow ponds and marshy areas on the tundra in the summer? | rainwater cannot soak into the permafrost |
| What kinds of plants are on the tundra? | mosses, grasses, shrubs, and dwarf forms of trees |
| What happens north of the Arctic circle in midsummer? | 24-hour sunshine |
| How do caribou find food in the winter? | they scrape snow away to find lichen |
| Why are there no tall trees on the tundra? | insufficient precipitation and permafrost prevents deep root growth |
| How are fish adapted to living in icy waters? | they produce chemicals that keep their blood from freezing |
| What part of a mountain is the warmest? | the base |
| What part of a mountain gets the most precipitation? | the peak |
| What's the climate at the top of a mountain called? | alpine |
