Usage tips
Separable verb
'Zusammenwirken' (to interact / cooperate) is a separable verb. In a main clause, the prefix 'zusammen' comes at the end of the sentence. In subordinate clauses and in the infinitive with 'zu', the verb stays together.
EXAMPLE
Verschiedene Faktoren wirken hier zusammen.
Various factors interact here.
Word structure
The word is made up of 'zusammen' (together) and 'wirken' (to act, to have an effect). So it describes how several elements jointly produce an effect.
EXAMPLE
Mensch und Natur wirken auf komplexe Weise zusammen.
Humans and nature interact in complex ways.
Typical subjects
This verb is not only used for people. Abstract subjects such as 'Faktoren' (factors), 'Kräfte' (forces), 'Komponenten' (components), or 'Medikamente' (medications), which jointly have an effect, are also common.
EXAMPLE
Mehrere Ursachen wirkten bei dem Unfall zusammen.
Several causes interacted in the accident.
Register
'Zusammenwirken' (to interact / cooperate) belongs more to formal or technical language. It is often used to describe complex interactions in systems, organizations, or science.
EXAMPLE
Das Zusammenwirken von Politik und Wirtschaft ist entscheidend für den Wohlstand.
The interaction between politics and business is crucial for prosperity.

zusammenwirken vs zusammenarbeiten
to collaborate / work together
'zusammenarbeiten' and 'zusammenwirken' are closely related because both express that several parts contribute to a result. 'zusammenarbeiten' is used especially for people, teams, or organizations that work together on a task. 'zusammenwirken' sounds somewhat more formal and can also say that different factors, forces, or technical parts interact to produce an effect. That is why 'zusammenarbeiten' is often more natural in everyday contexts involving people. 'zusammenwirken' fits better when you want to emphasize the shared result or effect.
zusammenwirken
Bei dem Unfall wirkten mehrere Ursachen zusammen.
Several causes interacted in the accident.
zusammenarbeiten
Die Mitarbeiterin arbeitet mit dem neuen Kollegen an einem Bericht zusammen.
The employee is working together with the new colleague on a report.
