Read the material and talk about your findings.

Material 1: In the vast wasteland of Alaska in North America, there is a kind of mouse, which feeds on vegetation and is extremely fertile. However, when the population is too prolific and causes serious damage to vegetation, the fur of some members will automatically turn bright and dazzling yellow to attract the attention of natural enemies. If natural enemies reduce the number of mice to an appropriate number, mice will rush to the cliff in droves, hug each other and throw themselves into the sea.

Material 2: Each group of Chinese Huangshan macaques is generally maintained at about 28, which is the critical point of the best survival state of the group, and the members of the group maintain this state with their lives-whenever the number of the group exceeds, the older monkeys will resolutely choose to fall off the cliff and die.

Exploration results: Animals understand the survival principle of nature and know that only by making good use of natural resources can race continue.
