Answer and Explanation:
In a cell, the smaller the surface area in relation to its volume, the lower the rate of diffusion. The ratio of surface area to volume of an object decreases sharply with increase in its size. The materials move across the cell rapidly because the cell has a larger surface area to volume ratio thus the rate of diffusion of materials is high.

B. Both primary and secondary succession involve ecosystems recovering from a disruptive event.
Explanation;
-Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field.
-Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. Secondary succession follows a major disturbance, such as a fire or a flood.
