True
False
Why are lagoons, like the one near Moana’s village, and wetlands important to both people and nature?
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.
They provide food and shelter for many species.
What could happen if people overfish in a lagoon or coastal area?
Fish populations would increase.
The coral reef could suffer.
Fish populations might decrease.
Other animals might lose a food source.
Pollution in one part of the ocean (like near Motunui) won’t affect other parts, such as coral reefs or lagoons.
False
True
What is the primary source of energy for all ecosystems, including coral reefs and forests?
The fish in the lagoon
The wind
The coconut trees
The sun
How do coral reefs, like those around Motunui, help their ecosystems?
They provide food and shelter for marine life.
They protect shorelines from strong waves.
They make sure sharks reach the coast line.
They keep water clean by filtering debris.
Why is biodiversity important to ecosystems like forests, oceans, or even cities?
It helps people grow more crops.
It ensures all species can support each other.
It makes the area more attractive to tourists.
It speeds up the growth of trees.
Why is it important for humans to only take what they need from nature?
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
To reduce waste
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 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.
