Ecosystems are balanced when every part plays an important role, from the smallest insects to the largest animals.
True
False
What is the primary source of energy for all ecosystems, including coral reefs and forests?
The coconut trees
The fish in the lagoon
The wind
The sun
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.
How do coral reefs, like those around Motunui, help their ecosystems?
They keep water clean by filtering debris.
They provide food and shelter for marine life.
They make sure sharks reach the coast line.
They protect shorelines from strong waves.
Trees, like coconut trees on Motunui, are vital for both humans and animals in many ecosystems around the world.
True
False
Pollution in one part of the ocean (like near Motunui) won’t affect other parts, such as coral reefs or lagoons.
True
False
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 dry, sandy locations.
They do not provide water for different plants and animals.
They are a natural barrier between the land and ocean.
What is an ecosystem?
A type of building
A group of people working together
A way of organizing animals
A system of connected living and non-living things
Plants, animals, and people depend on each other in all ecosystems, just like Moana depends on her island and the sea.
False
True
What could happen if people overfish in a lagoon or coastal area?
The coral reef could suffer.
Fish populations would increase.
Fish populations might decrease.
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 make sure ecosystems stay balanced
To avoid running out of resources like food and water
They actually need to take more, because it might run out
Why is biodiversity important to ecosystems like forests, oceans, or even cities?
It speeds up the growth of trees.
It makes the area more attractive to tourists.
It ensures all species can support each other.
It helps people grow more crops.
