When you watch TV programmes about wild animals.It is amazing to see how an African animal can(41)E a lion's attack.In the wilderness,every one has a stunt (绝技).Even plants have their own ways of fighting off enemies.
Over millions of years of(42)G,plants have developed a unique defence system.Chemicals are widely used for(43)J.By making their leaves,flowers,stems,roots and fruits(44)A or poisonous to animals,plants can fight back.
One such plant is the Golden Wattle tree.British (45)H David Cameron has found when an animal eats the tree's leaves,the amount of poisonous tannin(单宁) increases in the other leaves."It's like the damaged leaves(46)B the others telling them to fight together against the enemy,"he said.
The tree also sends defence messages to neighboring plants by giving out a special smell.Golden Wattle tree in the(47)E 45meters will get the message and produce more tannin within 10minutes.Now,if an animal eats too many of the trees'leaves,it will die.
Every species of plant or tree specializes in the production of a particular set of (48)F.A plant-eating animal that can safely eat the leaves of one tree may be poisoned by its neighbor.
In this way,plants have developed not only(49)C defence systems,but also shared them with others.This makes it impossible for a single animal to destroy even a small area of forest.
