Final answer:
An organization that is absorbed into the purchasing corporation and ceases to be a separate entity is experiencing an acquisition.
Step-by-step explanation:
When an organization ceases to exist as a separate entity and is absorbed into the purchasing corporation, this is known as an acquisition. During an acquisition, the purchasing organization typically maintains dominance and may integrate the acquired company's operations, staff, and assets into its own, often resulting in a consolidation of departments such as accounting and sales. This process can induce organizational stress similar to that experienced during downsizing and requires adjustments by the employees to new corporate cultures and structures.
