They have many ways to survive and help our planet. Let's learn about some special plants. The Venus flytrap is a meat-eating plant. It grows in places where the soil has little nutrition. Its leaves can close quickly when an insect touches them. Then it eats the insect to get nutrition. The cactus grows in deserts where there is little rain. It has thick stems to store water. Its leaves are like sharp spines, which help reduce water loss. The mangrove tree grows in salty water near the sea. Its roots grow above the ground to breathe air. These roots also help prevent the soil from being washed away by waves. All these plants show us how strong and clever they are. They can live in different environments and help keep our planet healthy. We should respect and protect all plants. 1．Why does the Venus flytrap eat insects? A．Because it likes the taste of insects.
