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
Ecosystems are balanced when every part plays an important role, from the smallest insects to the largest animals.
False
True
What could happen if people overfish in a lagoon or coastal area?
Fish populations might decrease.
Fish populations would increase.
Other animals might lose a food source.
The coral reef could suffer.
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.
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 provide food and shelter for many species.
They are dry, sandy locations.
They are a natural barrier between the land and ocean.
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.
Pollution in one part of the ocean (like near Motunui) won’t affect other parts, such as coral reefs or lagoons.
False
True
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
They actually need to take more, because it might run out
To make sure ecosystems stay balanced
Trees, like coconut trees on Motunui, are vital for both humans and animals in many ecosystems around the world.
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
What is an ecosystem?
A system of connected living and non-living things
A way of organizing animals
A type of building
A group of people working together
What roles do trees or palm trees play in ecosystems?
They are only there for humans to use their wood.
