The interesting facts about bees.
Scaning: Find the adjectives the writer uses to describe bees.
Imagine you go to the supermarket in your area, but there are almost no fruits, vegetables, honey, milk, eggs, or chocolate. How would you feel? Disappointed? Angry? Sad? At this moment you realize people, plants, and animals are all connected. We need each other to live, and bees are one of the best examples of this connection.
Bees are very hard-working animals, and their greatest work is pollination. On one trip, they often visit 50 to 100 flowers. As they fly from one flower to another, they take pollen with them. This action helps plants grow. In fact, without their work, about 80 per cent of the plants in the world cannot grow. For this reason, many scientists believe that bees are the most important animals on this planet.
We Can’t Live Without Bees
Bees are also one of the most interesting animals in the world. For example, they work hard together to make their homes. In order to store honey, they create honeycombs. Another interesting thing about bees is how they communicate. When a bee finds new food, it uses a dance to tell the others where and how far away the food is.
Bees play an important part in the ecosystem of our planet. However, the number of bees is dropping, and scientists are worried. Bees need our help, and there is a lot we can do. Think about what you can do to protect one of the most amazing animals on earth.
