Carnivorous plants don’t really eat meat. However, they catch insects or small spiders, because there aren't enough nutrients for them in the soil. There are over 600 different types of these plants.
Carnivorous plants grow everywhere in the world, except for Antarctica. They need more sun and water than other plants, so there aren't as many in the rainforest or the desert. They grow in soil that is too acidic or doesn't have enough nutrition for other plants, such as swamps. Otherwise, carnivorous plants wouldn't stand a chance against other plants, because carnivorous plants grow rather slowly.
Carnivorous plants have traps for small animals or insects. An insect falls into a kind of hollow space made of leaves. It can't get out because the walls are so smooth. Other carnivorous plants have sticky places that the prey gets stuck on.
