A tsunami is a secondary succession. this is because it supported vegetation life before a natural disturbance. The biome had reached its climax community and then it all got wiped out by the tsunami. So Indonesia needs to build up again. they started with regrowing coral and by now i am sure they have flourished. once the reefs are back, then the fish will come back along with their predators. which will have everything go back to normal. on land, they planted more coconut trees. because of all the dead stuff worms and mushrooms will have come back to feed. because the worms came back the birds will come back along with their predators. once everything is vegetated again and the animals have come back, indonesia willreach its climax communtiy once more.
