Question

how would an increase in nest sites affect a population of pigeons?
○ the population would decrease.
○ the population would increase.
○ the population would remain almost the same.
○ the population would be reduced the next year.

Explanation:

Nest sites are a resource for pigeons (a limiting factor). Increasing nest sites reduces competition for this resource, allowing more pigeons to reproduce and survive, so the population should increase. The other options (decrease, same, reduced next year) contradict this ecological principle.

Answer:

B. The population would increase.
