Question

primary succession occurs when a disturbance has occurred to completely wipe out an ecosystem and make it barren. what does barren mean? showing no signs of life or vegetation at all; a climax community; a flourishing ecosystem full of trees and vegetation; only moss and lichen inhabit the ecosystem

Explanation:

To determine the meaning of "barren" in the context of an ecosystem, we analyze the options:

• "A climax community" refers to a stable, mature ecosystem, not barren.
• "A flourishing ecosystem full of trees and vegetation" is the opposite of barren.
• "Only moss and lichen inhabit the ecosystem" describes an early stage of succession (pioneer species), not barren.
• "Showing no signs of life or vegetation at all" fits the definition of a barren ecosystem, as barren means lacking life or vegetation.

Answer:

Showing no signs of life or vegetation at all
