After a volcanic eruption, lava covers the land. What is the order that plants grow to repopulate the area?
Lichens → Shrubs → Grasses → Trees
Lichens → tree → shrubs→Grasses
Grasses → Lichens → Shrubs → Trees
Lichens → Grasses → Shrubs → Trees
Lichens are important to the creation of an ecosystem due to the fact that they create soil by
becoming tall
collecting water
reproducing asexually
weathering rock
What is the role that lichen or moss play in a primary succession?
pioneer species
keystone species
founder species
invasive species
What are the pioneer species for secondary succession?
lichen
moss
grass
algae
What is not the cause of primary succession?
hurricane
volcanic explosion
melting glaciers
landsliders
What is not the cause of secondary succession?
Strip mines
clean cutting
tornado
flood
Lichen look like tiny plants, but they’re actually a fusion between a algae and a fungus.The Alga feeds the fungus, and the fungus absorb water for alga and protects the alga from the environment.
What type of relationship is between algae and fungus?
Parasitism
competition
commensalism
mutualism

A.It happens before a natural disaster occurs
It happens on bare rock
It occurs after a natural disaster
A.Pioneer species time period is longer
Which of the following statements about succession is correct?
secondary succession occurs where no soil exists
primary succession occurs in areas where soil remains after a disturbance
secondary succession can occur where a disturbance has left soil intact
some cases of succession involve pioneer species, a phenomenon in which species inhibit the growth of newcomers
