How do plants fight for their existence?

In order to survive, different plants were able to adapt to different climatic conditions, even unfavorable ones. For example, a cactus in the desert has learned to retain moisture for a long time, since it is very dry in the desert and it rarely rains. Some plants are protected by their structure. As far as we know, nettles can “sting” us with their leaves and stems as soon as we touch them. This is also a defense with which she fights against survival. Let’s remember the Venus flytrap. It emits smell and sweet syrup in order to lure insects into its “mouth”, which it feeds on. All this is a struggle for survival.
