Topic 2.7: Ecological Succession
Learning Objective: ERT-2.I
Describe ecological succession.
Essential Knowledge: ERT-2.I.1
There are two main types of ecological succession: primary and secondary succession.
Essential Knowledge: ERT-2.I.2
A keystone species in an ecosystem is a species whose activities have a particularly significant role in determining community structure.
Essential Knowledge: ERT-2.I.3
An indicator species is a plant or animal that, by its presence, abundance, scarcity, or chemical composition, demonstrates that some distinctive aspect of the character or quality of an ecosystem is present.
Learning Objective: ERT-2.J
Describe the effect of ecological succession on ecosystems.
Essential Knowledge: ERT-2.J.1
Pioneer members of an early successional species commonly move into unoccupied habitat and over time adapt to its particular conditions, which may result in the origin of new species.
Essential Knowledge: ERT-2.J.2
Succession in a disturbed ecosystem will affect the total biomass, species richness, and net productivity over time.
