Example Question #141 : Ecology
During primary succession, when are pioneer species likely to be found in an environment?
During the summer
Near early stages of succession
Near later stages of succession
When many nutrients are available
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 #1 : Understand Differences Between Primary And Secondary Succession
Which would not be a cause of secondary succession?
Windstorm
Deforestation due to logging
Flooding
Lava flow
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
secondary species
primary species
pioneer species
keystone 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.
