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 an emergent in a tropical rainforest?

    • A small shrub that grows on the forest floor
    • A dead tree that rots on the forest floor and is slowly broken down by fungi and insects
    • A plant that grows on the trunk of another tree
    • A very tall tree that pokes out above the canopy

  3. What is the understorey?

    • The shady layer of smaller trees beneath the canopy
    • The thick roof formed by treetops in full sun
    • The tallest trees that stand above the canopy, with roots that reach deep into the soil
    • The dark, damp ground at the bottom of the forest

  4. What is a buttress root?

    • A thin root that grows deep into the soil for water and holds the trunk steady in storms
    • A large root that grows out sideways to hold up a tall tree
    • A root that grows upwards out of the soil to take in air
    • A root that stores food for the tree in the dry season

  5. What is a drip-tip?

    • A flower that opens only at night to attract moths and bats across the forest canopy
    • A sharp thorn that stops animals from eating the leaf
    • A pointed leaf tip that lets heavy rain run off quickly
    • A bud at the end of a branch that makes new leaves

  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. What is the main reason rainforest trees race upwards so strongly?

    • They grow tall to store water for long dry seasons, which are common in the rainforest
    • They grow tall to escape frosts that come each winter
    • They grow tall because the soil is poor and only found near the top
    • They compete for sunlight in a hot, wet climate where plants grow all year

  9. It is midday in a rainforest but the floor is very dark. What is the most likely reason?

    • The floor is always covered by water that blocks the light
    • The canopy blocks most of the sunlight before it reaches the floor
    • The Sun sets early in tropical rainforests, so the forest floor is dark by the middle of the day
    • The trees on the floor produce a dark pigment in their leaves

  10. Heavy rain falls in the rainforest. Which leaf feature best stops the leaf from rotting?

    • A pointed drip-tip that sheds water quickly
    • A soft, hairy surface that soaks up water
    • A thick, spongy stem that stores rainwater
    • A flat, wide leaf that holds water in a pool

  11. A rainforest leaf is waxy and shiny. Which problem does this adaptation help the leaf solve?

    • Heavy rain and strong sun, by shedding water and protecting the leaf
    • A long dry season with almost no rain, so the leaves need to store water for months
    • Too little sunlight reaching the forest floor
    • Cold frost that freezes the leaf overnight

  12. A very tall rainforest tree has wide buttress roots. Which problem do these roots solve?

    • The tall, heavy trunk could topple over, so the roots hold it steady
    • Animals on the forest floor keep eating the roots
    • The trunk has too little water to stay alive, so the tree needs roots that reach deep water
    • The base of the tree gets too little sunlight

  13. The Manaus graph shows about 27°C and rain every month. What does this mean for rainforest trees?

    • Trees grow only in the dry months when the Sun is strongest
    • Trees can grow all year, because it is hot and wet all year
    • Trees must drop their leaves each summer
    • Trees stop growing in the wet months

  14. A pupil says the canopy is the lowest layer of the rainforest. Which response is correct?

    • Yes, the emergents are lower than the canopy, because they grow in the shade beneath the canopy
    • Yes, the canopy is lowest because its trees grow downwards
    • No, the canopy is lowest because it sits on the damp soil
    • No, the forest floor is the lowest layer, and the canopy sits below the emergents

  15. If the canopy was cut down, what would most likely happen to the plants on the forest floor?

    • They would be unaffected, because the canopy has no link with the floor
    • They would grow taller at once to reach the new canopy above
    • They would receive much more sunlight, changing the shady conditions they are adapted to
    • They would be protected from heavy rain by the bare ground and would grow faster than before

  16. A rainforest tree has a pointed leaf tip. Which adaptation is this?

    • A thorn, which protects the leaf from being eaten
    • A root, which pulls water up from the soil
    • A bud, which produces new flowers each spring
    • A drip-tip, which helps rain run off the leaf

  17. Which pair correctly matches a problem to an adaptation?

    • Cold winters: buttress roots
    • Lack of sun on the floor: waxy leaves
    • Very tall trunk: thin, shallow roots
    • Heavy rain: drip-tip leaves

  18. Which statement best explains why rainforests have layers?

    • Layers are caused by the wind blowing leaves into separate piles
    • Plants compete for light in a hot, wet climate, so trees grow at different heights
    • Animals only live at specific heights, which forms the layers
    • Layers are built up by thin strips of soil added each year by rivers that flood the forest

  19. Why is the forest floor a difficult place for plants that need lots of light?

    • The floor is too hot for any plant to survive, because the sun shines directly on the ground all day
    • The floor gets so much rain that all plants are washed away
    • The floor is always frozen and covered in snow
    • The canopy blocks most sunlight, so only plants that cope with shade can grow there

  20. A rainforest animal has camouflage that matches the canopy. Which idea best links this to adaptation?

    • Camouflage is an adaptation that helps an animal survive in its habitat
    • Camouflage only helps animals that live in cold tundra, where snow hides them from predators
    • Camouflage is a problem caused by high temperatures in the forest
    • Camouflage is a layer of the rainforest, like the canopy
