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 percent of the plants in the world cannot grow. For this reason, many scientists believe that bees are the most important animals on this planet.

Can you give another title for the text
Bees have five eyes. They have two large compound eyes on the sides of their head and three small simple eyes (ocelli) on the top of their head, which help them detect light and navigate.
Different types of bees have different lifespans. For example, worker bees usually live for a few weeks during the busy summer months, while the queen bee can live for several years.
Bees can recognize human faces. They use their visual and olfactory senses to distinguish different human features.
2. What other interesting facts do you know about bees
Question 2
3. What do you know about the connection between humans and other insects, such as ants and butterflies
Question 3
Food source: Ants can be both beneficial and harmful to humans. Some ants help control pests in gardens by preying on small insects, which indirectly benefits human agriculture and horticulture. On the other hand, some ants can damage crops or invade homes in search of food, causing inconvenience to humans.
Ecosystem balance: They play a role in soil aeration as they dig tunnels, which helps improve soil structure and allows plant roots to grow better. This is beneficial for human-related plant cultivation.
