How wolves change rivers

 Introduction When wolves came back for being away for 70 years at yellowstone they changed our rivers.They also changed a lot of other things too.

P=2 Wolves killed a lot of animals which saved more animals because when they were away for so long the number of deer increased because there was no wolves to kill them.When they started killing them it led to more plants growing because the deer did not eat them.Then the trees started to grow and this was what it led to.

P=3 When the trees began growing in increase of singing birds and other birds was phenomenal.The increase of bears and beavers increased too because the birds sat on trees, trees gave berries on them which they ate and trees gave beavers wood to build All because of wolves.The wolves killed coyotes which made hawks, rabbits, beavers and pests all safe so the number of them started to increase too all because of wolves.

 P=4 Wolves helped rivers because of the plants and trees.When the water splashes soil came out from the sides because of the plants and trees made the water clean and helped above plus even more animals. 

Summary That’s the big impact wolves make in animals lives. Everything That I just talked about all happened because of wolves.So they do kill but they save more.
