Answer:
b. True
Explanation:
Behavioral ecology is a science that studies animal behavior, considering its evolutionary and ecological bases, in which through experiments it seeks ways to show the evolutionary / adaptive causes of behaviors. Ecoetology deals with functional questions about behavior, how a behavioral pattern contributes to the survival chances of an animal or group of animals and their reproductive success. In addition, behavioral ecology is a meeting point for the study of behavior, ecology and evolution, in which ecology is the stage on which the animal must perform its behavior, and evolution in which organisms will be selected for having higher behaviors. success.
For this reason, we can conclude that the study of behavioral evolution, emphasizing the role of ecological factors as agents of natural selection, is known as behavioral ecology.
