What reasons the spread of living organisms on land depends on?

The spread of living organisms on land is explained by a large amount of light, especially for plants that, with photosynthesis, produce nutrients for all other animals and oxygen. In this habitat, which, by the way, is called terrestrial-air, there is a lot of oxygen, which is necessary for breathing to all living organisms. The disadvantages of this environment include an insufficient amount of moisture, t.To. There are arid areas. The second drawback of lack of heat, especially the areas of the north and Antarctica.

In wet equatorial areas, where summer is summer, t.It is warm and hot, and, consequently, the feed base for animals is huge (four crops per year), then these tropical forests have a huge biological diversity. In the forests of a temperate belt, where there is a change of times: a warm summer and a harsh winter, therefore, the animal and plant world is not represented by such a variety as tropical forests. The feed base is limited, especially in winter.

The spread of living organisms is associated with the flow of light to earth. The more light, the faster living organisms grow and develop.

The first plants and insects appeared on Earth, the warmer under the rays of the sun, the more the day, the more humidity, the faster they grow and spread.
