When considering classical mathematics, the Greeks must be a main focus of our attention. In fact, the primary reason for discussing earlier mathematics is to understand what the Greeks inherited and what they left to their posterity.
The organisms that engage in primary succession are known as pioneer species. Typical pioneer species include simple lichens, algae, and fungi. These simple organisms begin breaking down the resources in the environment and make it suitable for the later introduction of more complex species, such as vascular plants.
In primary succession pioneer species like lichen, algae and fungi as well as other abiotic factors like wind and water start to normalize the habitat.Primary succession begins on rock formations, such as volcanoes or mountains, or in a place with no organisms or soil.This creates conditions nearer optimum for vascular plant growth; pedogenesis or the formation of soil is the most important process.n primary succession pioneer species like lichen, algae and fungi as well as other abiotic factors like wind and water start to normalize the habitat.
