Biomes and Net Primary Production Quiz

What are biomes characterized by?

• Their climates and typical plant and animal life

• Their size and shape

• Their location on Earth

• Their geological features

Which biomes are found in southern Africa?

• Tundra and taiga

• Desert and grassland

• Temperate forest and tropical rainforest

• Savanna and chaparral

Describe one ecosystem in a southern African biome.

• Tundra with frozen soil and low-growing vegetation

• Hot and dry desert with cacti and sand dunes

• Rainforest with dense vegetation and diverse animal species

• Grassland with tall grasses and grazing animals

Which abiotic conditions have the greatest influence on biome classification?

• Temperature and precipitation

• Wind speed and humidity

• Altitude and soil composition

• Sunlight intensity and air pressure

How are climatographs helpful in understanding biomes?

• They show the average temperature and precipitation for a biome

• They indicate the dominant plant and animal species in a biome

• They measure the net primary production of a biome

• They predict the weather patterns in a biome

What is the relationship between latitude and biomes located across Earth?

• Biomes become colder and drier as latitude increases

• Biomes become warmer and wetter as latitude increases

• Biomes remain the same regardless of latitude

• Biomes are randomly distributed across latitude

Why is natural selection important to biomes and organisms?

• It determines the climate of a biome

• It influences the distribution of organisms in a biome

• It controls the net primary production of a biome

• It regulates the water cycle in a biome

Why do different biomes have different characteristic organisms?

• Because organisms adapt to the abiotic conditions of their biome

• Because organisms migrate between biomes

• Because organisms compete for resources within a biome

• Because organisms reproduce at different rates in each biome

What does net primary production refer to?

• The total amount of biomass in a biome

• The mean monthly temperature in a biome

• The rate at which decomposers break down biomass

• The rate at which primary producers convert energy to biomass
