There is a population of birds that differ in feather, color, and in diet. The green feathered birds, eat fish, while red feathered birds eat insects. A drop hits the rabbits of this population. The drought has no effect on the insect population, but it dries up the pounds and the fish pound population decline. The main selective presser for the birds in this scenario is.
The main selective pressure for the birds in this scenario would be the decline in the fish population due to the drought. Since green-feathered birds mainly eat fish, this decline in the fish population would put them under pressure to adapt to a different diet or face a potential disadvantage in survival. On the other hand, red-feathered birds that mainly eat insects would not be affected as much, as their food source is not directly impacted by the drought. Therefore, natural selection could favor a shift in the population towards more red-feathered birds, which can survive on insects, and fewer green-feathered birds that rely on fish.
A. More common in a population
The correct answer is A. More common in a population.
To understand why this is the case, we need to look at how natural selection works. Natural selection is a process by which certain traits or variations within a population become more or less common over time, based on their impact on an organism's survival and reproduction.
When a particular variation provides an advantage to an individual -- meaning it allows that individual to survive better, reproduce more successfully, or both -- those individuals have a higher chance of passing on their advantageous traits to the next generation. As a result, the frequency of that advantageous variation increases within the population over time. This is because the individuals with the advantageous variation are more likely to survive, reproduce, and pass on their genes carrying that variation to their offspring.
On the other hand, variations that are disadvantageous -- meaning they reduce an individual's chances of survival or reproduction -- will become less common in the population over time. Individuals with these disadvantageous traits are less likely to survive, reproduce, and pass on their genes to the next generation. As a result, the frequency of these disadvantageous variations decreases.
So, when a variation provides an advantage in terms of survival and reproduction, it will become more common in a population through the process of natural selection.
