Compared with summer, what changes will happen to the external morphology or living habits of some animals and plants in winter? It is urgent to do business scientifically. Thank you!

The law of biological evolution is the generation of survival of the fittest. According to this law, the changes of organisms in summer and winter are to adapt to the changes of cold and hot environment. What we often see is that plants flourish in summer, with green leaves and red flowers, and plants wither and leaves are residual in winter.

The adjustment of animal shape, mainly the heat absorption and warmth retention function of hair: coarsening and thinning, and changing color depth.

Living habits, such as:

When winter comes, migratory birds migrate to the south, geese fly to the south, and swallows fly to the warmer south. ...

Summer comes, migratory birds move northward, swallows return, and geese fly to their hometown in droves. ...

When winter comes, most insects only put their eggs in a dormant state to survive the severe winter, and snakes, frogs and black bears begin to hibernate.

China's twenty-four solar terms in agricultural season is a scientific summary of the long-term production practice and exploration of the working people to adapt to the laws of nature, and it also contains the laws and requirements that the animals and plants on this earth must adapt to the climate and environment of the earth all year round.
