Answer:
Primary succession is the type of succession which occurs in areas where there was no form of life before or it occurs in areas where the previous form of life has fully been eradicated with not even the soil present from that ecosystem. For example, a land where lava eruption has occurred.
A secondary succession is the type of succession which occurs in areas where there was life before which was removed by natural disasters like fire, flood or by human activities. This kind of areas might have the soil texture and composition to support life again. But for primary succession, the rocks will eventually have to be broken down and soil particles would form with the passage of time. Then only the land will be able to support life. Hence, primary succession takes longer to occur.

Explanation:
The population of the birds must have been kept between 30 and 50 individuals by population limiting factors such as the presence of predators within the community or competition for resources such as food or spaces.
For the population to shoot up to 90 all of a sudden, it may be that one or more of the population limiting factors has been removed from the population. <u>It could be that a major predator has been removed from the community or the competition for food/space is now significantly reduced due to more food/space in the community. </u>
