Moana: Ecosystems in action

  • Why is biodiversity important to ecosystems like forests, oceans, or even cities?
    It ensures all species can support each other.
    It speeds up the growth of trees.
    It makes the area more attractive to tourists.
    It helps people grow more crops.
  • Trees, like coconut trees on Motunui, are vital for both humans and animals in many ecosystems around the world.
    True
    False
  • What is an ecosystem?
    A way of organizing animals
    A group of people working together
    A type of building
    A system of connected living and non-living things
  • Why are lagoons, like the one near Moana’s village, and wetlands important to both people and nature?
    They provide food and shelter for many species.
    They are dry, sandy locations.
    They do not provide water for different plants and animals.
    They are a natural barrier between the land and ocean.
  • How do coral reefs, like those around Motunui, help their ecosystems?
    They protect shorelines from strong waves.
    They keep water clean by filtering debris.
    They provide food and shelter for marine life.
    They make sure sharks reach the coast line.
  • Ecosystems are balanced when every part plays an important role, from the smallest insects to the largest animals.
    False
    True
  • What could happen if people overfish in a lagoon or coastal area?
    Fish populations would increase.
    Fish populations might decrease.
    The coral reef could suffer.
    Other animals might lose a food source.
  • What is the primary source of energy for all ecosystems, including coral reefs and forests?
    The coconut trees
    The wind
    The sun
    The fish in the lagoon
  • Plants, animals, and people depend on each other in all ecosystems, just like Moana depends on her island and the sea.
    True
    False
  • Pollution in one part of the ocean (like near Motunui) won’t affect other parts, such as coral reefs or lagoons.
    True
    False
  • Why is it important for humans to only take what they need from nature?
    To reduce waste
    To make sure ecosystems stay balanced
    They actually need to take more, because it might run out
    To avoid running out of resources like food and water
  • What roles do trees or palm trees play in ecosystems?
    They provide food and building materials.
    They store carbon to help reduce climate change.
    They are only there for humans to use their wood.
    They produce oxygen.
