Unit 4 Biodiversity, Biomes and Succession

Why do plants that grow in the tundra have shallow root systems

• they have no soil in which to grow.

• they cannot grow through the permafrost

• they are frequently soaked by heavy rains

• they are trampled each time animals migrate

How are tropical plants such as bromeliads adapted to the biome in which they live?

• They grow from tree branches rather than the forest floor, which helps them to absorb more sunlight.

• they have long, thick roots, which helps them to gather the nutrients that are found deep with in the soil.

• they have hollow leaves and stems for storing water, which helps them to survive long periods with little rainfall.

• they lose their leaves during the winter, which helps them to save energy when the temperature falls and prevents the buildup of snow.

In which biome would you expect to find a permafrost layer?

• taiga

• tundra

• grassland

• temperate rain forest

A researcher is investigating the plants shown below. Which biome is the researcher most likely studying?

• taiga

• desert

• grassland

• tropical rain forest

How is a tundra biome similar to a desert biome?

• both biomes have dry, rocky soils

• both biomes lack plants or animals

• both biomes are hot during the day and cold at night

• both biomes are characterized by very little precipitation

The picture shows and arctic fox. In which biome does the fox most likely live?

• desert

• tundra

• grasslands

• temperature rain forest

Which is an example of a biome?

• cave

• an old tree

• a large lake

• a tropical rain forest

You observe a garden in a schoolyard. Corn, tomatoes, pumpkins, and other crops thrive in the garden. What is most likely true of the soil in this microhabitat?

• it is dry and frozen

• it is rocky, sandy, and dry

• it is deep, dark, and nutrient rich

• it is thin, acidic, and nutrient poor.

What is one way that a temperate rain forest is different from a temperate deciduous forest?

• a temperate rain forest has large populations of grasses rather than tall trees.

• a temperate rain forest is made up of palm trees rather than coniferous trees.

• a temperate rain forest has a long rainy season rather than moderate, year-round rainfall.

• a temperate rain forest has trees that lose their leaves in winter rather than keeping them year-round.
