Question

How did bird beak size correlate with seed size? How does seed soze relate to precipitation?

Answer 1

The beak size of the birds is determined by the type of the seeds they eat.The birds with large beaks consume larger seeds and those with small seeds consume the smaller seeds.The birds adapted for their survival..

The seed size ans hape also depend upon the maount of precipitation .Larger seeds have a higher probability of germination when compared to the smaller ones. These plants had a higher survival rate and fecundity. The amount of precipitation determines the plant fecundity and as a part of natural selection the seeds in regions where there is higher precipitation are larger.
