Behavioral Ecology and Ecophysiology examine adaptations of the individual to its environment.
The study of the effects and causes of variation in behavioral traits among people is the primary research focus of the study group Behavioral Ecology & Ecophysiology. Most studies are conducted inside an ethological framework, emphasizing all four critical aspects of animal behavior: function, evolution, causation, and development.
Using an interdisciplinary and multidisciplinary approach, we study procreation and sexual selection in various animal communities, but primarily in birds. While our primary study area is behavioral ecology, our present research interests range from physiology to population dynamics.

Some of these can easily be eliminated by knowing that both nitrogen 14 and nitrogen 15 are isotopes ( same element, with the same amount of protons, but with different numbers of neutrons) of nitrogen. So if the only difference between nitrogen 14, 15 , and regular nitrogen is the amount of neutrons...how many protons and electrons should both nitrogen 14 and 15 have? After thinking, you should be able to eliminate A, B,and C.
