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