Biomes of the World

What are the characteristics of tropical rainforests?

• High levels of snowfall, low humidity, and limited plant and animal species

• Moderate levels of rainfall, moderate humidity, and limited plant and animal species

• Low levels of rainfall, low humidity, and limited plant and animal species

• High levels of rainfall, high humidity, and diverse plant and animal species

How do plants and animals adapt to the desert biome?

• Migration to cooler climates

• Hibernation during the hottest part of the day

• Increased consumption of water

• Specialized features to conserve water and withstand extreme temperatures

What are the main types of grassland biomes?

• Tropical grasslands and temperate grasslands

• Desert and tundra

• Rainforest and savanna

• Taiga and chaparral

What are the characteristics of tundra biomes?

• High temperatures, long growing seasons, no permafrost, and high biodiversity

• Low temperatures, short growing seasons, permafrost, and low biodiversity

• Extreme temperatures, unpredictable growing seasons, no permafrost, and high biodiversity

• Moderate temperatures, moderate growing seasons, occasional permafrost, and moderate biodiversity

Describe the different types of aquatic biomes.

• Desert and tundra biomes

• Freshwater and marine biomes

• Forest and grassland biomes

• Polar and temperate biomes

What are the main features of deciduous forest biomes?

• Shrubs shedding leaves annually, few plant and animal species, unpredictable temperatures

• Perennial trees, limited plant and animal species, extreme temperatures

• Evergreen trees, minimal plant and animal species, constant temperatures

• Trees shedding leaves annually, diverse plant and animal species, distinct seasons with moderate temperatures

What is the average temperature and precipitation in tropical rainforests?

• 60°F (15°C) and 100-300 inches (250-750 cm)

How do plants in the desert biome conserve water?

• Having shallow root systems

• Growing large flowers to trap moisture

• Shedding leaves frequently

• Deep root systems, water storage, and small leaves

What are the main threats to grassland biomes?

• Pollution and deforestation

• Urbanization and industrialization

• Drought and wildfires

• Habitat destruction, overgrazing, invasive species, and climate change

How do animals in the tundra biome survive the cold temperatures?

• Thick fur or feathers, storing extra fat, and hibernating

• Eating ice

• Wearing light clothing

• Building igloos
