Imagine that you're a happy fly. You're just flying around the sky when you see beautiful pink leaf. That looks like nice place to land to have a rest. As you rest your feet on the leaf, you notice something strange. You want to move. But in 0.6 second, you are caught by the plants! You will be digested（消化） as its food. Welcome to the world of carnivorous plants!
We call them carnivorous because they attract, catch, and eat insects. Like other plants, they get energy from the sun. But unlike other plants, they get their nutrients（营养素）from the insects they catch. They live in places where the soil is short of nutrients.
There are over 25,000 kinds of plants. Only 600 or so are carnivorous. The famous one is The Venus flytrap. Its leaves look like big mouths. When an insect flies to it, it will close its leaf like a man closing the mouth.
Pitcher plants might be the most interesting kind of carnivorous. They are in the shape of a deep bottle and can fool the insects into landing on them by offering sweet nectar（花蜜）.Then they wait for the insects to come. The insects will be caught by a "cover" that would close quickly the minute it goes in. Then the plant can enjoy the meal after digesting the insect.
