What changes have taken place in autumn?

I thought autumn was the harvest season, and it turned out that autumn was also the starting point of life. I summed up the changes brought by autumn:

1, most trees began to shed leaves, and the leaves were yellow and curly, falling from the trees and dancing with the wind.

The cold climate in the north is not suitable for geese to survive, so they will fly to the warm south in droves.

In autumn, the grass on the ground turns yellow gradually, and the leaves of deciduous trees begin to turn yellow and fall with the wind.

In autumn, there are great changes in plants, animals and weather, waiting for us to observe them carefully.
