Question

Lichens that colonize bare rocks are an example of a pioneer
species. In which environment would a pioneer species of lichen
be most successful?

Select one:
A:a grassland that has established itself on the site of an old farm

B:an old growth deciduous forest

C:a hillside that has been cleared by a volcanic eruption

D:a mountain meadow after a thunderstorm

Answer 1

Answer:

C. A hillside that has been cleared by a volcanic eruption.

Explanation:

Pioneer species are hardy species which are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by fire or other natural disasters. Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants.

Hope this helps!
