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.

Answer:
B) cryptic coloration
Explanation:
The plants have developed numerous different types to protect themselves from the herbivores because they tend to damage them or even totally destroy them. The development of certain chemicals that are unpleasant or poisonous for the herbivores is one of the defense mechanisms, like the development of nicotine or the highly toxic strychnine. Also, physical defense mechanisms that hurt the herbivores like the spines or thorns have been developed, making the herbivores think twice before they try anything as they can get hurt because of them. The cryptic coloration though is not a defense mechanism of the plants, but instead it is a defense mechanism that is used by the animals. This type of coloration is protecting the animals as it managed to blend them in with the environment, thus it is very hard to spot them, or it makes their shape much different in the eyes of the predators thus confusing them.
