The 20 questions

  1. Which rainforest layer is the thick, leafy roof of treetops?

    • The emergent layer
    • The understorey
    • The canopy
    • The forest floor

  2. What is the name for a very tall tree that pokes out above the rainforest canopy?

    • Understorey
    • Sapling
    • Shrub layer
    • Emergent

  3. What is the shady layer of smaller trees directly beneath the rainforest canopy called?

    • Understorey
    • Shrub layer
    • Forest floor
    • Emergent layer

  4. What type of large root grows sideways to help support tall rainforest trees?

    • Tap root
    • Buttress root
    • Bulb root
    • Prop root

  5. What is a pointed leaf tip that helps heavy rain run off quickly called?

    • Thorn guard
    • Waxy cuticle
    • Drip-tip
    • Stomata pore

  6. Which layer is the dark, damp ground at the bottom of the rainforest?

    • The forest floor
    • The emergent layer
    • The canopy
    • The understorey

  7. Roughly how tall can emergent trees grow in a tropical rainforest?

    • About 5 metres
    • About 150 metres
    • About 50 metres
    • About 15 metres

  8. Why do rainforest trees race upwards so strongly towards the light?

    • Heavy soil nutrients
    • Strong wind protection
    • Deep root systems
    • Intense light competition

  9. Why is the rainforest floor extremely dark even at midday?

    • Frequent heavy ash
    • Canopy blocks sunlight
    • Thick fog cover
    • Underground location

  10. Which leaf feature best prevents rot during heavy rainforest downpours?

    • Drip-tip
    • Hairy surface
    • Thick bark
    • Rough edges

  11. What dual purpose does a waxy, shiny leaf serve in a rainforest?

    • Sheds water and sun
    • Attracts pollinators
    • Stores liquid nitrogen
    • Absorbs heavy frost

  12. Which problem are wide buttress roots on tall rainforest trees designed to solve?

    • Topple prevention
    • Sunlight capture
    • Water storage
    • Nutrient absorption

  13. What does a hot and wet climate all year mean for rainforest trees?

    • Stunted growth
    • Continuous growth
    • Seasonal shedding
    • Dormant winter

  14. What is the lowest layer of the tropical rainforest?

    • Understorey
    • Canopy
    • Emergents
    • Forest floor

  15. How would removing the canopy affect plants on the forest floor?

    • Total darkness
    • Heavy flooding
    • Increased sunlight
    • Constant frost

  16. What is a pointed leaf tip on a rainforest tree called?

    • Waxy cuticle
    • Liana stem
    • Buttress root
    • Drip-tip

  17. Which plant adaptation helps shed heavy tropical rainfall?

    • Tap roots
    • Buttress roots
    • Thick bark
    • Drip-tip leaves

  18. Why do plants in a tropical rainforest form distinct layers?

    • Soil differences
    • Competition for light
    • Protection from wind
    • Nutrient shortages

  19. Why is the forest floor difficult for plants needing high light levels?

    • Frozen ground
    • Dry soil
    • High winds
    • Canopy blocks sunlight

  20. What type of survival feature is animal camouflage in the canopy?

    • Adaptation
    • Mutation
    • Migration
    • Hibernation
