DENDROLOGY

Detailed explanation-1: -Pioneer species prepare an area for other species in two ways. First, they break down rocks in primary succession, allowing later plant species to put down roots. Second, pioneer species often grow quickly and die back each year, adding organic matter to the soil they create by breaking down rocks.

Detailed explanation-2: -Pioneer species pave the way for more complex communities of organisms because the pioneers have altered the physical environment to make it more habitable. This leads to other forms of ecological succession. Once grasses and weeds begin to grow, soil formation is accelerated and more animal species begin to appear.

Detailed explanation-3: -In the beginning of succession pioneer species are able to start to rebuild the ecosystem, over time these organisms decompose and release nutrients to form a layer of soil larger, more complex can grow in. Algae or moss are examples of important pioneer species.

Detailed explanation-4: -Examples of pioneer species are lichens, algae, and fungi. These species are more tolerant and eventually contribute to the formation of the soil by breaking down rocks into smaller particles. They also provide organic matter to the area.
