Answer:
Basically, observation can be defined as the action or process of observing something or someone carefully or in order to gain information, in other words, watching or analyzing something so as to know more about it. For example, if a biologist wants to observe the behaviour of a specific kind of animal in the wild, that person will have to watch and focus on what that animal usually do, what it usually eats, how it hunts or find food, etc, in order to know more about the animal itself.
