J H TARAPORE SCHOOL SUB: ENGLISH LANGUAGE (2020-2021) STD IX A/B/C/D Revision Worksheet -4

1. 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. How important is the Amazon River for Amazon rainforests?

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

4. Why is there very little air movement in the understory?

5. What is the layer above the understory called?

6. Find the word from the passage which means ‘grand’.

3. Letter Writing:

a. Your sister has passed the Class VIII exams with 95% marks. However, she gets confused which stream of
