The core in biology refers to the central or innermost part of a biological structure, such as a cell, organism, or ecosystem. It is often essential for the functioning and stability of the system.
In cell biology, the core may refer to the nucleus of the cell, which houses the genetic material (DNA). It is responsible for controlling the cell's activities and is essential for cell division and replication.
In ecology, the core of an ecosystem refers to the central area with the highest species diversity and stability. This core area is crucial for maintaining the balance of the ecosystem and supporting various ecological processes.
