determine whether the following disturbances will be followed by primary or secondary succession. in coastal areas, wind moves sand, blowing away or engulfing the soil, and eventually creating sand dunes: the introduction of livestock to an area leads to over - grazing that removes native grasses: a forest is cleared to gather lumber used for building houses: a lava flow down the side of a volcano destroys all vegetation and eventually turns into volcanic rock when it cools and hardens: done

Answer

Brief Explanations:

  1. In coastal areas, wind - blown sand creating dunes is primary succession as it starts on a substrate with no soil or existing organisms.
  2. Introduction of livestock leading to over - grazing is secondary succession since there was pre - existing vegetation and soil.
  3. Clearing a forest for lumber is secondary succession as the area had an existing forest community and soil.
  4. A lava flow destroying all vegetation and turning into volcanic rock is primary succession as it creates a new, barren substrate with no pre - existing life or soil.

Answer:

  1. Primary succession
  2. Secondary succession
  3. Secondary succession
  4. Primary succession
