The environment includes the species' responses to moisture, temperature, and nutrients, their biotic relationships, availability of flora and fauna to colonize the area, chance dispersal of seeds and animals, soils, climate, and disturbance such as fire and wind. Barring major disturbances, it will persist indefinitely. In contrast, pre-existing nitrogen-fixing plants (or any pre-existing plant communities) are uncommon to nonexistent in an area with no established soil system.

An example of pioneer species, in forests of northeastern North America are Betula papyrifera (White birch) and Prunus serotina (Black cherry), that are particularly well-adapted to exploit large gaps in forest canopies, but are intolerant of shade and are eventually replaced by other shade-tolerant species in the absence of disturbances that create such gaps. The formation of organic material in these areas typically occurswith the accumulation ofwind-carried soil erosion, nutrients deposited by flowing bodies of water, and erosion of bedrock. (a) identify the oldest stage of succession shown in the figure above. (d) The forests shown in the, 1. A more rigorous, data-driven testing of successional models and community theory generally began with the work of Robert Whittaker and John Curtis in the 1950s and 1960s. Ecosystems: Change and Challenge The Structure of Ecosystems Ecosystem: a dynamic, stable system characterised by the interaction of plants and animals with each other and with the non-living components of the environment The components of an ecosystem are categorised as either biotic and abiotic Biotic means the living environment, components Primary Succession (Picture Credits: NIOS Environment) The first plant to colonize an area is called the pioneer community.
