“3D photorealistic illustration of Bronfenbrenner's ecological systems theory, designed as a funnel-shaped layered structure (wide top, narrow bottom). The bottom tip of the funnel is an orange glossy sphere labeled 'The individual' with subtext 'Sex, Age, Health etc.'. Surrounding the sphere (ascending the funnel) are concentric, transparent gradient-colored layers: Microsystem (yellow layer): Labels 'Family, School, Peers, Religious group, Neighborhood play area' Mesosystem (purple layer): Connects Microsystem elements with blue arrows Exosystem (light blue layer): Labels 'Friends of family, Health services, Mass media, Social welfare services, Legal services, Neighbors' Macrosystem (light green top layer): Label 'Attitudes and ideologies of the culture' The funnel sits on a dark green rectangular base (Chronosystem), with text: 'Chronosystem: Patterning of environmental events and transitions over the life course; sociohistorical conditions' + a vertical green arrow labeled 'Time (sociohistorical conditions and time since life events)'. Style: Highly detailed 3D rendering, glossy material texture, clear typography, professional educational diagram, dark background to emphasize layers, accurate label placement as shown.”
