Outline two reasons why the climax community in the succession model shown above is more stable than the intermediate community.
Distinguish between zonation and succession.
Outline two ways in which the food web is likely to change as a result of succession.
Outline two ways in which the soil quality in the pioneer stages of the succession model shown above will differ from that in the climax ecosystem.
