Question

“What is the effect of the type of food available on the frequency of different types of bird beaks?” The the lab procedure you just studied should help you address this question. Will it? Explain.

Answer 1

The lab procedure will help me answer this question. The experiment will track the increase or decrease in certain flocks. If a flock is struggling to eat, or successful in eating, then the flock will either shrink or grow. This change in the number of birds within the flock will be an effect of the limitation of types of food available. Thus, this experiment will help illustrate the effects of the type of food available on the frequency of different types of bird beaks.

Answer 2

If the food type changes in a given environment, then the amount of each type of bird beak will change as birds with beaks more suited to the available food will consume more successfully over time. The independent variable of the lab is the type of food that is available to the birds. The dependent variable of the lab is the frequency of each type-size and shape-of beaks. The conclusion will state that favourable traits place one species in a more optimal position to survive in a given envronment.
