(Đọc phần thứ hai của văn bản và trả lời các câu hỏi.)

Elephants are a keystone species, and they play an important role in maintaining biodiversity. Below are some examples.

While looking for food, elephants pull down trees and break up thorny bushes, which helps to create grasslands for other animals to inhabit. In addition, they use their feet to dig up salt licks that are rich in nutrients for themselves and for other animals. Their footprints also create deep holes that water can collect in. Other species rely on this water source in the dry season.

Most importantly, elephant droppings are vital to the environment. Animals such as baboons and birds pick up undigested seeds and nuts from these droppings for their food. This type of waste also works as a kind of manure, which helps humans to have fertile soil to plant their crops. Elephant droppings are also a vehicle for dispersing seeds and making them grow. Some types of seeds will not germinate unless they have passed through an elephant’s digestive system. So, if elephants become extinct, those seeds would not grow into trees, leading to an increase in soil erosion and flooding.

What would happen if there were no more elephants on Earth? Elephants maintain the ecosystems in which they live, and make it possible for a lot of other plant and animal species to survive in those environments as well. In a nutshell, if elephants become extinct, many other species will disappear.

Key

1 . They create grasslands when they pull down trees and break up thorny bushes while looking for food.

2. They get water that is collected and stored in deep holes created by elephants’ footprints.

3. Baboons and birds get their food from undigested seeds and nuts in elephant droppings.

4. Humans can have rich soil which is fertilised by elephant droppings.

5. Some kinds of seeds cannot grow into trees naturally. They can germinate only after passing through an elephant’s digestive system

6. If elephants become extinct, there will be fewer trees, leading to soil erosion and flooding, and many other species will disappear.

7. (Suggested answer) In a brochure for wildlife protection. The rhetorical questions (e.g. Why is there c day for elephants? What would happen if there were no more elephants on Earth?) are used to persuade or influence readers. These questions do not really ask for the answers; they serve to emphasise a point or just get the audience thinking.
