Can plants catch animals?

                   Plants growing in bogs and peaty areas often need to supplement their food supply by catching insects. Bog water contains very little nitrogen, but some bog plants can obtain this substance by catching and digesting insects. They are known as insectivorous plants. Some have vase-shaped structures, into which insects are lured by bright colours and scents, like flower nectar. They fall into a slippery funnel and drop into a pool of liquid containing digestive juices. Other insectivorous plants are covered with sticky tentacles that trap flies. The most remarkable is the Venus’s flytrap plant. It has two clawed plates that slam together when a fly walks over them and touches a trigger hair.

                      Other insect-eating plants are aquatic, catching tiny crustaceans in bladder-shaped-underwater traps. Some of the largest insectivorous plants live in the tropical rainforests of Southeast Asia. They produce hanging, vase-shaped traps as big as a fist.
