Question
A bird population nested along the banks of a river and fed off fish. After new homes were built along the river, the bird population declined. A change to which limiting factor was most likely responsible?
space water weather sunlight
Solution
The most likely limiting factor responsible for the decline in the bird population is "space". Here's why:
-
The question mentions that new homes were built along the river. This means that the natural habitat of the birds, which was along the river banks, was taken over by human habitation.
-
Birds, like all animals, need a certain amount of space to live, find food, and reproduce. This is known as their habitat. If their habitat is reduced or destroyed, it can lead to a decline in their population.
-
The other options - water, weather, and sunlight - are less likely to be the cause. The question does not mention any changes to the water or weather. And sunlight is usually not a limiting factor for birds, as they can fly to areas with more sunlight if needed.
So, the construction of new homes most likely reduced the available space for the birds, leading to a decline in their population.
