In this scenario, the drought leads to the complete loss of plants, which are essential for food for some of the birds.
- Bird A eats insects and plant seeds, so with the loss of plant seeds, its food source is partially affected. However, if there are still insects available, Bird A may still survive.
- Bird B depends solely on flower nectar. With plants wiped out entirely, Bird B loses its primary food source and is likely to die.
- Bird C eats plant seeds as well, so its survival is also compromised due to the absence of seeds.
Given this analysis, the likely outcome is that Bird B will not survive, and both Birds A and C may struggle but can survive if there are insects available for Bird A. The most fitting outcome is:
D ) Bird A survives; either bird B or bird C dies, and the other survives.
This option correctly indicates the unlikeliness of Bird B's survival and allows for the possibility of Bird A and Bird C's fates being interdependent based on the remaining food resources.
