Primary
Secondary
The process in which a community changes through time
ecological succession
biodiversity
evolution
ecosystem resilience
Occurs in an area that has never before been colonized
primary succession
natural disturbance
ecological resilience
secondary succession
Occurs in a formerly inhabited area that was disturbed.
primary succession
natural disturbance
ecological resilience
secondary succession
Lichens are important in primary succession because they
help to break down rocks to create soil
provide a soft place for seeds to germinate
are fire-resistant
are gymnosperms, which are important for resilience
A non-living part of an ecosystem that affects its environment
biotic factor
abiotic factor
disturbance
resistance

the growth of trees on it
Which of the following best describes primary succession?
Volcano wipes out ecosystem that gradually grows back from ash covered soil
Volcano creates a new island of rock that must break down to form an ecosystem
Forest fire burns down forest that must bounce back over time
Tornado destroys a crop that must slowly grow back over time.
The graph shows the biodiversity of a forest over time.
A disturbance happened at point A. What could that disturbance have been and what type of succession is seen in the graph?
A volcanic eruption led to secondary succession
A forest fire led to primary succession
A flood led to secondary succession
A tornado led to primary succession
What type of succession is seen in the graph?

What type of succession is seen in the graph?
Primary succession because it starts with no life
Secondary succession because it starts with no life
Primary succession because it increases the number of individuals
Secondary succession because it increases the number of individuals
What type of succession is seen in the graph?
Primary succession because species decline drastically
Secondary succession because species decrease after a disturbance, then rebound
