True
False
What is the primary source of energy for all ecosystems, including coral reefs and forests?
The fish in the lagoon
The sun
The wind
The coconut trees
How do coral reefs, like those around Motunui, help their ecosystems?
They protect shorelines from strong waves.
They keep water clean by filtering debris.
They provide food and shelter for marine life.
They make sure sharks reach the coast line.
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 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?
They actually need to take more, because it might run out
To reduce waste
To avoid running out of resources like food and water
To make sure ecosystems stay balanced
