READ THE EXTRACT CAREFULLY AND ANSWER THE FOLLOWING QUESTIONS BY CHOOSING THE BEST OPTIONS.
1. The Amazon is the world’s largest tropical rainforest. It covers an area of nearly 2.8 million square miles, which is nearly the size of the continent of Australia. The Amazon rainforest gets its name and life from the majestic Amazon river, the world’s second largest river, which runs directly through the heart of the region. The vast forest itself consists of four layers, each layer has its own ecosystems and specially adapted plants and animals.
2. The forest floor is the lowest region. Since only two per cent of the sunlight filters through the top layers of the rainforest , very few plants grow here. The forest floor, however, is rich with rotting vegetation and the bodies of dead organisms, which are quickly broken down into nutrients and decomposers.
3. The understory is the layer above the forest floor. Much like the forest floor, only about 2-5 per cent 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. Plants rely on insects and animals to pollinate their flowers.
4. The layer above the understory is the canopy. This is where much of the action in the rainforest occurs. Many canopy leaves have specially adapted leaves which form “drip tips”. Drip trips allow water to flow from the leaves which prevents mosses, fungi, and lichens from occupying the leaves. Leaves in the canopy are very dense and filter about 80 per cent of the sunlight. The canopy is where the wealth of the rainforest’s fruits and flowers grow.
