The Important Three: Mangroves, Tundras and Coral Reefs
What's an Ecosystem?
An ecosystem is all the living things (like plants, animals) and non-living things (such as water, rocks) in one area. Ecosystems can be big or small — from a small garden pond to a large icy tundra. Each ecosystem has a job, helping to keep a balance between its parts and the world.
1. Mangroves: Coast Protectors
Mangroves grow in coastal (海岸的) areas, mostly in warm places. They cover only a little of the world's coasts. But these strong trees are great for coasts! Their twisted roots are like a net. They stop the shore from being washed away in storms. Also, mangrove forests are home to many sea animals. Baby fish hide in the roots, and birds make nests in the branches. So, mangroves are like the "guards" of the coast, protecting land and sea life.
2. Tundras: Cold Lands
Tundras are cold, treeless areas in the Arctic and on high mountains. They cover about 10% of Earth's land. The ground there is often frozen — we call this permafrost. Even though it's hard to live there, tundras have special life. Small plants like mosses grow close to the ground to stay away from cold winds. Some animals, like Arctic hares, have thick fur to survive. Tundras store a lot of carbon in their frozen soil. This makes them important for the planet's climate, like Earth's "cold storage".
3. Coral Reefs: Ocean Homes
Coral reefs are underwater ecosystems. They form in warm, shallow (浅的) ocean waters and cover less than 1% of the ocean floor. But they're like busy cities under the sea! Thousands of colorful fish, sea turtles, and other creatures live here. Coral is made by tiny animals called polyps. These polyps build hard skeletons. Coral reefs also protect coasts from big waves. They're the "ocean homes" that support countless lives and shield shorelines.

( ) 2. Why are tundras called Earth's "cold storage"?
A. Because they are very cold with ice.
