Compare rates of succession: primary succession such as on new lava flow vs secondary succession in a forest that recently burne
Serggg [28]

Answer:

The answer is option D "Succession rates would depend on the number of early arriving facilitator species"

Explanation:

Ecologists have a solid interest in knowing how communities structure and change over the long run. Indeed, they have invested a ton of energy seeing how complex communities, such as forests, emerge from void land or uncovered stone. They study, for instance, locales where volcanic eruptions, ice sheet retreats, or out of control fires have occurred, clearing land or uncovering rock.

In examining these destinations over the long haul, ecologists have seen steady cycles of progress in natural communities. As a rule, a community emerging in an upset territory experiences a succession of movements in synthesis, frequently throughout numerous years. This arrangement of changes is called natural succession.

Succession is a progression of reformist changes in the structure of an ecological community over the long run.

In primary succession, recently uncovered or recently shaped stone is colonized by living things unexpectedly.

In secondary succession, a territory recently involved by living things is upset then recolonized following the aggravation.
