Which pair of scenarios correctly identifies examples or characteristics of primary and secondary succession?
Primary succession occurs in an area where trees are abundant. Secondary succession occurs after a fire disrupts an ecosystem, and the ecosystem is overtaken by new species.
Primary succession commonly includes lichens and mosses as pioneer species. Secondary succession occurs when an ecosystem starts on bare rock, where no other species have lived.
Primary succession may occur in an ecosystem destroyed by a hurricane. Secondary succession occurs when new sand dunes are formed.
Primary succession can include the process of lava cooling to form rock, which is then broken down to form soil in which plants can grow. Secondary succession occurs on land that was once cleared for farming.
