In the invasion-succession model, what happens when a group enters an area whose characteristics differ from the existing group?

• A. Integrates
• B. Displaces
• C. Coexists
• D. Migrates

Answer: (B)

Invasion-succession focuses on how a new group moving into a neighborhood with different characteristics tends to push out the existing group. The arrival of the newcomers changes the area so that the original residents are displaced—often through housing market pressures, shifting amenities, and social networks that favor the new group. This is why displacement best describes what happens. Integrating or coexisting would imply blending or sharing space without the turnover of residents, while migrating refers more to people moving, not the neighborhood undergoing a demographic shift caused by the newcomers.
