The Secret Language of Ants

When you look at the ground in a garden, ants seem like simple, quiet insects. They just run around in the dirt. However, scientists have long known that ants actually "talk" to each other. They do not use words or loud sounds. Instead, they use a secret system based on smell. Experts often call this system a "chemical language."

How do ants build this special network? Tiny chemicals called pheromones are dropped on the ground as an ant walks. Over time, these drops form an invisible trail across the soil. Because this trail connects food to the nest, other ants can easily follow it to find meals. Food gives the colony the energy it needs, so this shared trail helps the whole group survive and grow strong.

Inside the nest, there are also baby ants that cannot yet care for themselves. They often live in deep, dark rooms, and they cannot search for their own food. Worker ants take care of this problem: they feed the babies with soft, liquid food, mouth to mouth. This constant care helps the young ants grow safely until they are ready to work.

Ants also warn each other about danger. If a hungry bird attacks a worker, that ant releases a special warning chemical. Nearby ants quickly sense this signal and understand that danger is near. Then, many ants get ready to defend the nest together, making the bird decide to leave. This kind of teamwork shows just how connected ant communities really are.

What does the first paragraph suggest about how people usually see ants?

  • People often misunderstand what ants are really doing.

  • People can smell the same chemicals that ants use.

  • People mainly notice how fast ants can run.

  • People easily understand the sounds that ants make.

The use of invisible chemical trails suggests that the ant colony _____.

  • often has trouble finding food nearby
  • depends on sharing food as a group
  • prefers to eat outside the nest
  • moves around the dirt without any plan

According to the passage, which statement about the baby ants is true?

  • They grow faster than the worker ants do.

  • They are not able to find food by themselves.

The way the colony responds to a bird attack shows that its defense _____.

  • depends on each ant escaping alone
  • only happens when the Queen gives an order

  • works because the ants act together as a group

  • is mainly meant to hide the nest from danger

If you have ever hiked through thick clouds on a high mountain, you probably noticed that your face quickly became quite wet. Mountain fog actually consists of millions of microscopic water droplets floating gently in the cold atmosphere. In dry mountainous regions where regular rainfall is incredibly rare, brilliant engineers are successfully using this abundant natural moisture to solve serious daily water shortages. They have constructed massive mesh nets to harvest clean drinking water, and these tall, unique structures closely resemble giant volleyball nets. When strong mountain winds blow the thick fog through the nets, the invisible water vapor condenses rapidly onto the rough plastic threads. As more fog passes through, the tiny droplets combine to form much heavier water drops that eventually slide down into a large collection bucket. These impressive atmospheric water generators currently provide enough fresh water for entire isolated farming villages to survive comfortably during severe summer droughts. While the basic technology is surprisingly cheap to install and maintain, environmental researchers are continuously testing new net materials to improve the daily water collection rate. This wonderful scientific invention simply captures the local mountain weather perfectly. Therefore, it clearly proves that sustainable environmental solutions are often hiding right in front of us.
