Biology: Biodiversity and Human Impact

A species that is not native to an area is called: 

• Native Species
• Natural Species
• Invasive Species
• Symbiotic Species

Why do the populations of invasive species grow so quickly? 

• Invasive Species are native to an area. 
• Invasive species are prey to many animals.
• Invasive species have no predators.
• Invasive species keep the ecosystems in equilibrium.
