Answer:
With the scarcity of small seeds there will be a drastic change in the population of small-billed birds.
Step-by-step explanation:
As small-billed birds feed on small seeds, the scarcity of these seeds will cause major problems for this population. In the short term, the population of small-billed birds will decrease, as they will suffer from a lack of food. The rest of the population will go through a process of natural selection and will have to adapt and evolve to be able to feed themselves. Those who are not "selected" will die.
