8、he Amazon rainforest.In the Amazon rainforest5RainforestsTropical rainforests are forests where it rains a lot.In fact,a tropical rainforest receives between 150 and 400 centimeters(59157 in)of rain every year.They are also warm.The temperature ranges from 25 to 35 Celsius(77F95F).Rainforests are gr

9、een year-round.Their hot and humid climate is perfect for tall trees and other plants.The really thick parts of rainforests are what we call jungles.Tropical rainforests cover a small part(about 6 percent)of Earths surface.But more than half(50 percent)of the worlds plant and animal species are foun

10、d in them!Rainforests are usually near Earths equator.Most of the worlds rainforests are in Africa,Southeast Asia,and South America.The Amazing Amazon Level U6The AmazonThe Amazon rainforest is in South America.It is the largest tropical rainforest in the world.It has more kinds of insects,plants,an

11、d animals than any other place on Earth.Every year,scientists discover new species of insects and plants here.The Amazon River flows through the heart of this rainforest.Thousands of other rivers and streams empty into it.Many fish and other animals live in the Amazon River.This book will take you t

12、hrough the Amazon rainforest.You will travel from the tallest trees to the rainforest floor.Along the way,you will meet an eagle,monkey,jaguar,and ant.You will even hear what they would sayif they could talk.The rainforests dense foliage7So just how big is the Amazon River?The Amazon River can be mo

16、 poison arrow frog has super-bright colors.These colors warn other animals that its skin is poisonous.Sammy“Slowpoke”Sloth9Chapter 2:Layers of the RainforestTo better understand the rainforest,scientists have“divided”it into four parts.You can think of it like a four-story building.The highest trees

17、 make up the top floor,or the emergent layer.The next highest trees make up the canopy layer.Below them is the understory.At the bottom is the rainforest floor.High Risers The tallest trees of the rainforest are called the emergents.They are like umbrellas that rise above the thick forest.Emergents

18、receive lots of sun,wind,and rain.Big roots support these giant trees.Because the soil isnt deep,tree roots often grow above the ground.The kapok tree,for example,has roots that extend out like wooden walls.These roots are so big that your whole class could hide behind just one of them!Not many anim

19、als live in the emergent layer.Some birds and butterflies eat the leaves and fruit.One huge bird,the harpy eagle,actually lives there,high above the river.Rainforest LayersEmergent LayerCanopy LayerUnderstory LayerRainforest FloorThe Amazing Amazon Level U10Spotlight interview:The Harpy EagleRAZ Int

20、erviewer:Hello there,Harpy.Is it true that you are the largest eagle in the Americas?Harpy:I think so.I am about one meter tall,which is more than three feet high.RAZ Interviewer:It looks as if you have some big wings as well.Harpy:Oh,these things?I was born with these.If I stretch them out like thi

21、s,they are longer than most people.You see?My wingspan is two meters acrossabout six and a half feet.Flying fast really helps me find food.RAZ Interviewer:What is your favorite food?Harpy:Oh,I like pizza delivered to my door.Just kiddingI hunt sloths,monkeys,and other birds.Monkeys are probably my f

22、avorite.RAZ Interviewer:Is that what your big talons are for?Harpy:Yep.They can scoop unsuspecting animals right off tree branches.Hey,theres a monkey now!Ill see you later!Harpy eagle11Crazy Canopy The rainforests real action is in the canopy layer.This is where most plants and animals live.It is l

23、ike a thick roof made out of tree branches and vines.Many trees in the canopy are covered with climbing vines and epiphytes.Epiphytes are plants that grow on top of other plants.Most of the rainforests flowers,fruit,and seeds are found in this layer.With so much good canopy food,it makes sense that

24、animals hang out here.Many animals rarely go down to the ground.They spend their whole lives up in the trees.Sloths,toucans,and parrots are just some of the animals that live in the canopy.Howler monkeys are probably the loudest.Their name fits their behavior,as these monkeys howl and scream to keep

25、 other animals out of their territories.Bromeliads are cone-shaped plants that grow on trees.Their cones catch a lot of rainwater and form little swimming pools high above the ground.Tiny frogs,salamanders,and crabs live in these pools.Mosquitoes and dragonflies lay eggs in them.The Amazing Amazon L

26、evel U12Spotlight interview:The Howler MonkeyRAZ Interviewer:Wow,that was one loud howl!Would you please stop screaming for one moment?I would like to ask you a few questions!Howler:Okay,but hurry up.If I dont scream like this,other monkeys may come into our territory.RAZ Interviewer:Do you always s

27、tay up here in the canopy?Howler:This is our home,my man.On the ground,there are some really big animals its a jungle down there.Up here,we can eat fruit,leaves,and flowers,and we can live in safety.RAZ Interviewer:Does your long tail help you?It looks prehensile.Howler:Yeah,if by prehensile you mea

28、n“grab onto.”My tail helps me climb,but my hands and feet are very useful for climbing,too.RAZ Interviewer:You sure use big words for a monkey.Hey,stop the howling!If you can be heard from miles away,just think how loud it is for me.What makes you so loud anyway?Howler:I have a special bone in my wi

29、ndpipe.My throat is like a hollow sound box.RAZ Interviewer:Okay,Mr.Monkey,you can go back to howling now.13The Darker Story The understory is the third level of the rainforest.It is below the canopy and above the ground.This is where ferns,plants,and young trees grow.It is dark in the understory be

30、cause very little light shines through the thick canopy.Understory plants grow leaves that are big and wide to catch more sun.Animals like to eat these big leaves.The understory is not nearly as busy as the canopy,but animals do live here.Poison arrow frogs hide in the leaves.Snakes wrap around tree

31、s like vines.Birds eat insects from the wood.Large cats such as jaguars leap between branches.Howler monkeyJaguarThe Amazing Amazon Level U14Spotlight interview:The JaguarRAZ Interviewer:Hey,put me down!And dont bite.Bad big cat!Jaguar:Sorry,I thought you were a monkey.What are you doing here anyway

32、?RAZ Interviewer:I came to talk to you,the biggest cat in the Americas.Mr.Jaguar,are you really 2.6 meters(8.5 ft.)long?Jaguar:Thats what they say.I weigh 136 kilograms(300 lb),too.Not many animals mess with me.You can call me Jag.RAZ Interviewer:Okay,Jag,what do you do for exercise?Jag:I get bored

33、with just one sport.Thats why I cross-train:I run,swim,climb,and fish when I hunt.RAZ Interviewer:What do you hunt?Jag:Sometimes I climb up in the canopy to eat sloths and monkeys.On the ground,I hunt peccaries,tapirs,and yummy capybaras.On lazy days,I lie near the river and catch fish.When Im reall

34、y hungry,I kill caimans.RAZ Interviewer:Wow,I dont want to be in your powerful jaws ever again!Excuse me,I need to go now.15Reaching the TopScientists have found creative ways to study the top layers of rainforests.They have climbed with ropes and ladders.They have built platforms like tree houses.S

35、ome have gone up in cranes.A blimp has even lowered a raft of scientists down to the canopy.Chapter 3:Keeping It CleanIf you walked around the rainforest floor,you might be surprised.It is not just one thick jungle.Sure,you would see roots,plants,and baby trees.But most of the green would be high ab

36、ove you.Earthworms,termites,fungi,and bacteria eat up the fallen fruits and parts of trees.They recycle it back into nutritious soil.When a big tree falls,they munch it down into small pieces.Also on the ground are animals like deer,tapirs,peccaries,and capybaras.But there are far more spiders and b

37、ugs.Ant highways crisscross the rainforest floor.One kind of ant even parades around with leaves and flower petals in its mouth.It is the famous leaf-cutter ant.Rainforest floorThe Amazing Amazon Level U16Spotlight interview:The Leaf-Cutter AntRAZ Interviewer:Hey down there!The one carrying the big

38、leaf over your head!May I ask you a few questions?Ms.Ant:Sure,but I do need to hurry back to the fungus garden.Were low on food.RAZ Interviewer:Did you really just climb up a tree and cut off that leaf?Ms.Ant:Yes,and now Im carrying it back to our underground home.Thats where smaller ants will chew

39、it up into spongy bits.RAZ Interviewer:So you dont eat the leaf?Ms.Ant:No,we use the leaf bits to grow the fungus that we eat.Want some?RAZ Interviewer:No,thank you.I just had lunch.So tell me,what is it like underground?Ms.Ant:We have deep nests with lots of rooms.In the middle rooms,small ants ten

40、d to our fungus gardens.Our queen is in a different room.She can lay up to thirty thousand eggs in one day.Thats why there are almost five million of us here!Now if youll excuse me,I need to sniff my way home.And please watch your feetif you step on our trail,I might get lost!Leaf-cutter ants17Chapt

41、er 4:Who,Me?Yes,you.Do you like to eat bananas or chocolate?Does your bicycle have rubber tires?Well,guess what!Bananas,chocolate,and rubber all grow in the Amazon rainforest.Many more things come from the Amazon,too,such as medicines and pineapples.The Amazon is a treasure.Insects buzz by that have

42、nt been named yet.Trees grow,fall,and turn back into soil.And rainforest plants take carbon dioxide from the air and replace it with oxygen.Humans and other animals need oxygen in order to live.The Amazon rainforest is a real place.As you read these words,a jaguar moves through the understory.Right

43、now,a leaf-cutter ant marches back to a fungus garden.Somewhere in the Amazon,the scream of a howler monkey echoes through the forest.Can you hear it?The Amazon rainforest is home to many living things.The Amazing Amazon Level U18Explore MoreDid you like learning about the Amazon rainforest?Well,the
