Final answer:
Synergy refers to the increased effectiveness resulting from combined action or cooperation, affecting multiple areas such as bureaucracies, biology, event planning, and international trade.
Step-by-step explanation:
The increased effectiveness that results from combined action or cooperation is known as synergy. This concept applies widely, from biological interactions to business and trade.
In bureaucracies, synergy can lead to increased productivity and efficiency. In the biological context, cooperative interactions within organisms promote efficiency in using energy and matter.
Similarly, in business and event planning, partnering with organizations can lead to expanded outreach, diversity among attendees, and cost-effectiveness through combined resources. The concept of synergy is also evident in economics, where the division of labor and specialization can lead to increased productivity and economies of scale, not just at the national level but also internationally through trade.
