Question

Invasive species often cause large amounts of damage to an ecosystem. In 3–5 sentences, explain 3–5 characteristics that give them an advantage over native species

Answer 1

1. High reproductive rate and rapid growth let invasives establish large populations quickly and outcompete natives for space and resources.
2. Broad environmental tolerance and generalist diets enable them to survive varied conditions and exploit many food sources where specialists cannot.
3. Escape from natural predators, parasites, and diseases in the new range (enemy release) reduces mortality and allows unchecked population expansion.
4. Strong dispersal abilities or aggressive competitive traits (e.g., allelopathy, shading) let them spread fast and directly suppress native species’ recruitment and survival.
