Answer 1

To find the correct table that matches the scenarios to the type of succession, it's important to understand the definitions of primary and secondary succession:

• Primary Succession occurs in lifeless areas where there is no soil, such as after a volcanic eruption forms an island or when a glacier retreats and exposes bare rock.
• Secondary Succession occurs in areas where a disturbance has destroyed an existing community but soil and some organisms still remain, such as after a wildfire or a flood.

Given this understanding, let's evaluate each scenario from the tables provided:

1. A wildfire burns down a forest - This is a secondary succession because the soil and some organisms remain after the fire.
2. A glacier retreats to expose rock - This is primary succession because it starts on bare rock with no soil.
3. A volcano erupts and creates an island - This is primary succession, as it creates a new landform with no soil.
4. A hurricane causes a flood - This is secondary succession as it typically affects established ecosystems but does not completely strip the soil.
5. An earthquake causes a landslide - This is typically secondary succession, as the landslide may disturb existing vegetation but not necessarily remove the soil.

Now we can match these scenarios with the correct type of succession:

• Wildfire: Secondary
• Glacier retreat: Primary
• Volcano eruption: Primary
• Hurricane flood: Secondary
• Earthquake landslide: Secondary

Based on these evaluations, the correct matching would look like this:

• A wildfire burns down a forest - Secondary
• A glacier retreats to expose rock - Primary
• A volcano erupts and creates an island - Primary
• A hurricane causes a flood - Secondary
• An earthquake causes a landslide - Secondary

Table B is the only table that matches the scenarios with the established type of succession correctly:

B. Scenario Type of Succession a wildfire burns down a forest secondary
a glacier retreats to expose rock primary
a volcano erupts and creates an island primary
a hurricane causes a flood secondary
an earthquake causes a landslide secondary

Therefore, Table B is the correct match.
