Question 1: Which defining feature best distinguishes a biome from a smaller habitat?
Human-made landscaping and agriculture patterns
Soil type only, regardless of climate or vegetation
A large area with a characteristic climate and typical plant and animal communities
The presence of a single keystone species that controls the ecosystem
Question 2: Based on the material, why are tropical rainforests especially rich in species?
They are mostly underwater environments
They are warm, wet year-round and support dense, layered plant life
They have extreme seasonal freezing that limits predators
They receive less sunlight than other biomes
Question 3: If a region has four distinct seasons with trees that lose leaves in autumn, which forest type does the video describe it as?
Tropical rainforest
Savanna grassland
Taiga (boreal) forest
Temperate deciduous forest
Question 4: Which adaptation most helps plants survive in desert biomes described in the material?
Floating leaves adapted to saltwater immersion
Water-storing structures or reduced leaves to limit evaporation
Thin bark and large broad leaves to capture sunlight
Brightly colored flowers that open only at night to attract predators
Question 5: Why are grasslands especially good habitats for large grazing animals, according to the video text?
They offer extensive open areas with abundant grasses for grazing
They have dense tree cover that hides predators
They are primarily frozen wetlands with permafrost
They receive year-round heavy rainfall supporting lush forests
Question 6: Which statement best summarizes how aquatic biomes were categorized in the source material?
Subterranean aquifers as the sole marine biome
Freshwater biomes (lakes, rivers, wetlands) and marine biomes (oceans, coral reefs, estuaries)
Only saltwater zones classified by depth but not freshwater
Urban ponds and agricultural irrigation channels only
Question 7: Given the descriptions, which biome would most likely support polar bears and why?
Arctic tundra and polar ice regions because they are cold year-round with frozen ground and sea ice
Hot deserts because sparse vegetation reduces competition
Freshwater lakes because they provide open water year-round
Temperate deciduous forests because of seasonal leaf drop
