Theories of macroecology have only recently been applied to microbiology and so much remains to be understood about this growing field. Without using equations, make a claim about the motion of block 3 in terms of balanced or unbalanced forces. Each transitional community that is formed and replaced during succession is called a stage in succession or a seral community. A landscape ecologist observes in area right after a volcanic eruption.

Unless otherwise specified, the domain of a function is assumed to be the set of all real. [12], The trajectory of successional change can be influenced by site conditions, by the character of the events initiating succession (perturbations), by the interactions of the species present, and by more stochastic factors such as availability of colonists or seeds or weather conditions at the time of disturbance.

For example, soil changes due to erosion, leaching or the deposition of silt and clays can alter the nutrient content and water relationships in the ecosystems. By contrast, a forest fire can typically be characterized as secondary succession because the soil remains intact and the ecosystem can typically recover much quicker because of that fact.
