What could happen if people overfish in a lagoon or coastal area?
Fish populations might decrease.
The coral reef could suffer.
Fish populations would increase.
Other animals might lose a food source.
Why is it important for humans to only take what they need from nature?
To reduce waste
To avoid running out of resources like food and water
To make sure ecosystems stay balanced
They actually need to take more, because it might run out
How do coral reefs, like those around Motunui, help their ecosystems?
They keep water clean by filtering debris.
They protect shorelines from strong waves.
They provide food and shelter for marine life.
They make sure sharks reach the coast line.
What is an ecosystem?
A group of people working together
A way of organizing animals
A system of connected living and non-living things

Why is biodiversity important to ecosystems like forests, oceans, or even cities?
It ensures all species can support each other.
It helps people grow more crops.
It speeds up the growth of trees.
It makes the area more attractive to tourists.
Trees, like coconut trees on Motunui, are vital for both humans and animals in many ecosystems around the world.
False
True
What roles do trees or palm trees play in ecosystems?
They are only there for humans to use their wood.
They produce oxygen.
They provide food and building materials.
They store carbon to help reduce climate change.
Plants, animals, and people depend on each other in all ecosystems, just like Moana depends on her island and the sea.
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 are dry, sandy locations.
They provide food and shelter for many species.
They do not provide water for different plants and animals.
What is the primary source of energy for all ecosystems, including coral reefs and forests?
The sun
The coconut trees
The wind
The fish in the lagoon
Ecosystems are balanced when every part plays an important role, from the smallest insects to the largest animals.
True
False
Pollution in one part of the ocean (like near Motunui) won’t affect other parts, such as coral reefs or lagoons.
