Answer:

c. the cost to growth of allocating resources to defense

d. consistent fitness benefits of high allocations to defense

Explanation:

In order to ensure survival by  escape of  grazing and browsing by herbivores (and insects) plant usually adopt different defence mechanisms.This forms the basis for the optimum defence hypothesis .

The basic idea of the hypothesis is that the type   of  defence that an organism e.g plant  will adopt  against an herbivore depends on its fitness, and since this involve expenditure of energy it will be expensive for the organism to afford and maintain.

Data was collected concerning Galapagos bird beak size over time. There are several species finches, and they are also known as
astra-53 [7]

Finches adapt to the new conditions such as drought by changing the size, shape and depth of their beaks. Beak morphology varies according to drought conditions. Since after the drought, vegetation dries out and the hard, big, tough seeds remain, only the finches with deep beaks will survive. Finches adapt via their beaks to different foods sources and different local conditions.
