biology chapter 15.3

mountains are not considered biomes because they have

a climate that changes with elevation

the uppermost branches of trees form a(n)

canopy

a semi-arid/coastal desert has cool winters followed by long, warm summers

coastal

a(n) _______________________ tree keeps its needles all year long

coniferous

a(n) _______________________ tree loses its leaves in the autumn

deciduous

dry climate, plants that are adapted to store water, many animals are nocturnal to avoid daytime heat

desert

few/many plants grow in the tundra because of a layer of frozen soil called permafrost

few

-dominated by grasses with scattered trees and shrubs -definite dry season during the warm months of the year -habitat for large hoofed animals and for burrowing animals

grassland

a temperate deciduous forest has more/less precipitation than a temperate rain forest

less

one of the main characteristics of chaparral is long, hot summers/warm, wet summers

long, hot summers

polar ice caps are not considered biomes because they have

no soil or specific plant community

-long, cold winters and short, cold summers -dominated by coniferous trees and furry mammals

taiga

-dominated by coniferous or deciduous forest -some forests have hot summers and cold winters; others have a long wet season and dry summers

temperate forest

-warm temperatures, abundant rainfall year-round -lush forests with thick treetop layers that are home to a huge variety of species

tropical rain forest

tropical/temperate grasslands have a wet season and a dry season. tropical/temperate grasslands have a dry summer and a wet late spring and early summer

tropical; temperate

-long winters with below-zero temperatures and little precipitation -ground is permanently frozen

tundra
