Answer
- The grasshopper population will increase.- The skunk population will decrease.- The vulture population will decrease.
Explanation
In a food web, each organism depends on another for food, forming a complex network of feeding relationships. Reviewing the implications of the extinction of a bird, which likely preys on certain organisms and is prey for others, can lead to various changes in the population dynamics of the other species.1. If the bird preys on grasshoppers, its extinction would remove a predator, potentially causing the grasshopper population to increase.2. If the bird is prey for the skunk, its extinction would reduce the food supply for the skunk, potentially causing a decrease in the skunk population.3. Conversely, if the bird preyed on organisms that eat grasshoppers, its extinction might decrease competition for grasshoppers, allowing their population to flourish, not decrease.4. If the bird is prey for vultures and there are fewer birds, vultures might face a food shortage, causing their population to decrease.5. Increased grasshopper population could result in more consumption of grass, leading to a decrease rather than an increase in the grass population.
