After reading
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.
Discuss the questions.

3. What do you know about the connection between
humans and other insects, such as ants and butterflies
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.

3. What do you know about the connection between
humans and other insects, such as ants and butterflies
After reading
Pollination: Like bees, butterflies are important pollinators. They transfer pollen from one flower to another while feeding on nectar, which helps plants reproduce. This is crucial for the growth of many plants that humans rely on for food, medicine, and ornamental purposes.
Indicator species: Their presence or absence can indicate the health of an ecosystem. A decline in butterfly populations may signal environmental problems such as pollution or habitat loss, which also ultimately affects human-living environments.

Imagine you are the writer. Write one more paragraph about bees and add it to the text.
1e
To protect bees, we should try our best. There are many ways we can do. First, we can plant bee-friendly flowers and plants in our gardens or balconies. These provide bees with nectar and pollen. Second, avoid using pesticides as they can harm bees. Instead, try natural pest-control methods. Finally, spread the word! Let more people know the importance of bees and encourage them to join in protection efforts.
