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