In the biological ecosystems theory, which system includes the individual's immediate relationships such as family and peers?

• A. Exosystem
• B. Macrosystem
• C. Microsystem
• D. Chronosystem

Answer: (C)

The microsystem level includes direct, daily interactions and relationships the individual has with people they encounter regularly, like family, close friends, and teachers. Because these are the people and settings the person interacts with face-to-face and influences their development on a day-to-day basis, this level best fits the description of immediate relationships such as family and peers.

Other levels describe different influences: the exosystem involves settings that affect the person indirectly through someone else’s experiences (for example, a parent’s workplace); the macrosystem covers broad cultural values, laws, and norms; the chronosystem adds the dimension of time, capturing changes over life stages and generations.
