Why can there be a reduction in the species composition in the plant community?

The reduction in the species composition in the plant community can occur for a number of reasons. First, there is competition. All plants are fighting for a “better place in the sun”, while with the growth of some, the death of others occurs, the displacement of species. Secondly, eating a species by insects or animals is grazing. Third, climate change. For example, an increase in temperature, even by a degree, leads to the disappearance of a number of plant species. Fourth, the influence of man on nature, from uncontrolled collection of plants to indirect influence, for example, the construction of a hydroelectric power station.
