Biomes
Thinking Questions
When settlers first came to the northeastern United
States, they cut down trees to clear land for farming. Native Americans taught settlers how to tap maple trees to make sugar. What biome did these settlers
find themselves in? How do you know?
The temperate deciduous forest
biome; maple trees are deciduous
How do coral reefs form?
Animals called corals secrete calcium
carbonate shells. When the corals die, their shells remain
and build up, forming reefs.
What are wetlands and where are they
located?
Land areas that are covered with water most of the year; located in regions that lie between
solid land and water
Describe characteristics of
organisms that live in intertidal zones.
They are adapted to dramatic changes in
temperature, moisture, and
salinity, and can withstand the force
of wave action.
Why are estuaries among the most
productive ecosystems on
Earth?
Estuaries receive tons of nutrients
washed from inland soils, so their nutrient
levels are very high.
How are grassland and tundra biomes
similar?
Both are treeless and flat. Both have
freezing temperatures in
winter. Both receive small amounts of
precipitation. Both include grazing
animals.
What are the four zones of the Tropical
Rain Forest?
Forest floorUnderstory
CanopyEmergents
Why is much of the desert bare ground?
Lack of water
What is the biggest climactic difference
between a temperate rain forest and a tropical rain
forest?
Tropical rainforests are
warmer and tend to have higher precipitation
Why does the soil of tropical rain
forests make poor farmland?
A high level of rainfall tends
to wash nutrients from
the soil.
