Read the following passage and choose the option (A, B, C or D) that best answers each of the questions below.
Tropical rainforests have layers of life. The uppermost layer is called the canopy. Very mature, tall trees out their branches and leaves, nearly blocking out the sun in some places. Many animals live high in this green, leafy habitat. you can find monkeys, tree frogs and many different species of birds.
Below the treetops is a second layer, called the understory. The understory is shaded by the canopy. Not as much sunlight reaches the plants in the understory. Bushes and growing trees make up the understory. It is home to birds, reptiles and small climbing animals.
The third layer, the forest floor, is busy with life. Vines, shrubs, mosses, ferns, flowers and large predator animals, such as jaguars, can be found there. Small animals dig into the ground and live in bushes. Leaf-cutter ants and other insects busily hunt for food and water.
