The coral reef could suffer.
What is an ecosystem?
A type of building
A way of organizing animals
A group of people working together
A system of connected living and non-living things
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?
They actually need to take more, because it might run out
To make sure ecosystems stay balanced
To reduce waste
To avoid running out of resources like food and water
What is the primary source of energy for all ecosystems, including coral reefs and forests?

The fish in the lagoon
The sun
The wind
What roles do trees or palm trees play in ecosystems?
They are only there for humans to use their wood.
They produce oxygen.
They store carbon to help reduce climate change.
They provide food and building materials.
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 a natural barrier between the land and ocean.
They are dry, sandy locations.
They do not provide water for different plants and animals.
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 ensures all species can support each other.
It helps people grow more crops.
How do coral reefs, like those around Motunui, help their ecosystems?
They protect shorelines from strong waves.
They provide food and shelter for marine life.
They make sure sharks reach the coast line.
They keep water clean by filtering debris.
