An area that was covered by a glacier
Primary succession is a method of bringing about fertility in infertile land that can not be cultivated. This method usually involves plant species known as "pioneer species", that do not rely heavily on soil nutrients but add nutrients to the soil. The land under the glacier is likely to be void of nutrients and infertile, so primary succession will be needed there the most.
Photosynthesis. Figure 2.3: Photosynthesis: In the process of photosynthesis, plants convert radiant energy from the sun into chemical energy in the form of glucose - or sugar. Water (6H2O) + carbon dioxide (6 CO2) + sunlight (radiant energy) = glucose (C6H12O6) + Oxygen (6O2).
