Which of the following communities is more vulnerable to invasion by outside animals and plants?

1. Tropical evergreen forests
2. Oceanic island communities
3. Mangroves
4. Temperate forests

Correct answer: Oceanic island communities

Solution

Oceanic island communities are especially vulnerable because they are geographically isolated and often have many endemic species with limited defenses against new predators, competitors, and pathogens. This makes invasions by outside plants and animals more likely to spread and cause major disruption.
