Question 2
Plants are important to the development of karst formation primarily because
A) they provide the calcium carbonate necessary for karst topography to form.
B) they lessen the impact of raindrops on the surface so the water can more rapidly flow into stream channels.
C) the decay of large roots below the surface produces cavities which eventually enlarge to form caves.
D) they supply organic acids that enhance the dissolution process.
E) openings adjacent to their roots serve as microchannels that allow water to enter the rock.
Connell's experimental manipulation of species indicated the presence of competition.
