Example Questions
Example Question #1 : Understand Differences Between Primary And Secondary Succession
During primary succession, when are pioneer species likely to be found in an environment?
When many nutrients are available
During the summer
Near early stages of succession
Near later stages of succession
Near early stages of succession
Pioneer species are the first species to colonize an environment, and thus would be found in the early stages of succession.
Example Question #2432 : Ap Biology
Which would not be a cause of secondary succession?
Lava flow
Deforestation due to logging
Windstorm
Flooding
Lava flow
Primary succession occurs in an environment without previous life, or a barren habitat. Secondary succession occurs in an area that had previously been inhabited but experienced a disturbance, such as a lava flow. Secondary succession occurs in environments that have been distrubed, but have some remaining soil and vegetation.
Example Question #1 : Understand Differences Between Primary And Secondary Succession
The first species to inhabit an area after a disruption area called
keystone species
primary species
secondary species
pioneer species
pioneer species
The first species to inhabit an area that has been disrupted are called pioneer species. This is true in both primary and secondary succession. These pioneer species are hardy species that can withstand harsh conditions.
