What effect will an invasive species have on the carrying capacity of an ecosystem?

• The carrying capacity will increase
• The carrying capacity for everyone will decrease
• The carrying capacity will only decrease for those in competition for same resource
• The carrying capacity for all animals will stay the same

Kudzu has overgrown many parts of southern Missouri and native ground plants have disappeared from the area. This is an example of:

• Parasitism between kudzu and the native plants
• A predator prey relationship between ground plants and kudzu
• Competition occurring between the native and invasive species
• Commesalism occurring between the kudzo and native plants

1. What makes a species invasive?

• A specie that is local and has lived in the same place
• A specie who has come from another state or country
• A specie that has no "home" and travels for its whole life
• None of the above

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.
