Movement of individuals in and out of a population

Step 1: Define emigration

In ecology and population biology, emigration refers to the movement of individuals out of a specific population or geographic area. A helpful memory trick is to associate the letter "E" in emigration with exiting.

Step 2: Compare with the given options

• "when individuals move out of, or exit, a population": This matches the definition of emigration perfectly.
• "when no one moves in or out of a population": This describes a closed population with zero migration.
• "when individuals move into a population": This describes immigration (associate the letter "I" in immigration with moving in).
