Answer:
The answer is: microsystem.
Explanation:
The ecological systems theory suggests that the different environments and contexts in which a child develops function as ecological systems. The author of this theory organized these different systems according to the level of external influence. The most immediate system in which a child develops and interacts with others, is called a microsystem. A microsystem can be the child's home, school or community. It canbe any immediate setting in which the child experiences face-to-face relationships, activities and social roles.
