Answer:
A particular population limiting factor or factors must have been removed
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>
Ecosystems equilibrium is when populations of organisms in the ecosystem are balanced.
Forest fires actually help the environment, they remove plants and trees that are useless and leave space for new plants and trees to grow. After 26 years after the fire, the forest will start to grow again and will be green once again.
Have a nice day! :)
