Biomes

Tropical rainforest, arctic tundra, savanna, and taiga are names given to regions of the world called biomes. In which of these biomes would you find the greatest biodiversity? The greater the biodiversity in an ecosystem, the more likely that ecosystem will be sustainable, maintaining diversity and staying healthy.

• Tropical Rainforest
• Arctic Tundra
• Desert
• Taiga

Even a small area, such as a schoolyard, contains many microhabitats. Each microhabitat would probably contain a wide variety of organisms. What would the organisms in a single microhabitat have in common?

• They would all be about the same size
• They would all depend on each other for food and shelter
• They would all be the same species
• They would not have anything in common

The century plant is a succulent cactus plant with shallow roots and thick skin to prevent loss of water. It blooms after 20 to 30 years of growth. This plant would most likely be found in which ecosystem?

• Brazil's rain forest
• New Mexico's desert
• Antarctica's ice cap
• Colorado's mountains

Human beings are responsible for reducing the biodiversity of organisms in most biomes. Which is not a cause of this reduction?

• Paving roads
• Planting native seedlings
• Building houses
• Increasing hunting of animals

A student noticed on their trip that all animals had short coats with large ears, were mostly active around dawn and dusk, and all plants had shallow roots with waxy coverings around each plant. Which biome did this student visit?

• Tundra
• Desert
• Temperate Deciduous Forest
• Taiga

Cactus plants have thick, fleshy stems; shallow roots; & leaves in the form. All of these structures make a cactus suited for life in an arid environment. Of the following, the environment in which a cactus can best survive is a –

• desert
• grassland
• deciduous forest
• lake ecosystem

• taiga
• tundra
• marine
• Both B & C are true

The main factors that determine a biome are?

• temperature and precipitation
• altitude and topography
• latitude and longitude
• biodiversity and competition
