Answer:
The curve will become convex
Explanation:
A survivorship curve is a graph that displays the proportion of individuals capable of surviving based on their age ranges or other population parameters such as, for example, the survival rate of males and females. A Type III survivorship curve has a concave shape because individuals exhibit a high death rate immediately after birth. Examples of species that show a Type III curve include, among others, insects, fishes and small mammals.

Answer:
Disruptive selection is acting on the beak size in seedcrackers.
Explanation:
There are different types of natural selection: sexual selection, stabilizing selection, directional selection, frequency-dependent selection, and disruptive selection.
Disruptive selection occurs when selective pressure favor homozygous. In equilibrium, the two alleles might be present. If there are extreme factors in an environment, such as the seed type, that favor one or the other allele, then both alleles appear in a homozygous state.
The disruptive selection causes an increase in the two types of extreme phenotypes over the intermediate forms. Limits between one extreme and the other are frequently very sharped. Individuals belonging to one phenotype can not feed on the same seeds as individuals belonging to the other phenotype, due to the traits differences between them, competition, or predation.
Both extreme phenotypes are favored over intermediated forms.
