Question

I.Read the passage given below and answer the questions that follow:

The Amazon is the world’s largest tropical rainforest. It is roughly the size

of the continent of Australia and covers an area of nearly 2.8 million

square miles. The Amazon rainforest gets its life from the majestic Amazon

River which runs through the heart of the region. Amazon is also the

second largest river in the world. The rainforest is simply the drainage

basin for the river and its tributaries. The vast forest consists of four

layers, each featuring its own ecosystems and specially adapted plants

and animals.

The forest floor is the lowest region. Since only two percent of the sunlight

can filter through the top layers to the understory very few plants grow

there. The forest floor, however, is rich with rotting vegetation and bodies

of dead animals which quickly break down and get integrated into the soil

as nutrients. Tree roots stay close to these available nutrients and

decomposers such as millipedes and earth worms use these nutrients for

food.

The understory is the layer above the forest floor. Much like the forest

floor, only about 2 to 5 percent of the sunlight reaches this shadowy realm.

Many of the plants in the understory have large, broad leaves to collect as

much sunlight as possible. The understory is so thick that there is very

little air movement. As a result, plants rely on insects and animals to

pollinate their flowers.

The layer above the understory is the canopy. This is where much of the

action in the rainforest occurs. Many plants growing in this layer have

specially adapted leaves with drip tips. Drip tips allow water to flow off the

leaves and thus prevent mosses, fungi and lichens from infecting the

leaves. Leaves in the canopy are very dense and filter about 80 percent of

the sunlight. The canopy is where the wealth of the rainforest’s fruits and

flowers grow.

Answer the following questions.

1. Which is the world’s second largest river? (2)

2. How important is the Amazon River for Amazon rainforests?(2)

3. Why do very few plants grow in the understory of the rainforests?(2)

4. Why is there very little air movement in the understory? (2)​

Answer 1

Answer:

Question1. The Amazon is the world's second largest river.

Answer 2

Answer:

Amazon River is 2 largest river.

as Amazon rainforest is important for Amazon River because if there is a rain that will fall in the river that's why it is important as by it there will form a river.

they grow very little because they have no air there.

because they have very big leave which do not let air to go down.
