Ecology, Biomes, and Ecological 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.

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.
