Why do animals and plants respond to weather changes?

First, because the metabolism of animals and plants is carried out at a certain temperature, when the environmental temperature changes, we can make corresponding changes to maintain our metabolism and make it run normally, so that we can live at a normal temperature. For example, in winter, our feet are very cold, so we can only run to promote our body to produce heat to maintain our body temperature, or to increase our heat production by shivering and goose bumps.

Second: all the responses made by animals and plants are to adapt to environmental changes, for example,

When ants get in the way, it will rain. When ants move, it will rain.

Before the rain, there was more water in the air, and the ant nest became wet, which made the ants unable to live peacefully and leave the ant nest.

Dragonflies fly low, and there is no Feng in the rain.

Before the rain, the air pressure was low, and insects mostly floated at low altitude. Dragonflies often fly two or three meters above the ground for food, which is a sign that it is going to rain.

Third: plants also know the weather.

A: In summer, willow leaves droop and sway with the wind, which is a kind of scenery. However, if the willow leaves turn white, it indicates that rainy weather is coming. In fact, if you look closely, you will find that it is not that the willow leaves turn white, but that they will all turn over before the rainy day. The reverse side of the willow leaves is light green and there is a layer of "white frost" on the surface. If you are interested, you may wish to observe and verify it before and after the summer and autumn rainy days.

B: Usually, the top of the pumpkin vine grows slowly downward, but if the top of the pumpkin vine is generally upward in the summer morning, it indicates that the weather will turn from sunny to rainy. On the contrary, if the top of pumpkin vine is generally downward in rainy weather, it indicates that the weather will clear up.

Summary: Animals and plants have sensitive sensory organs, which can feel the changes of temperature, moderation, air pressure and wind and rain in nature and make corresponding responses.
