Are Invasive Species All Bad? |
Step by step
Solved in 2 steps
- What is an invasive species? Why are they destructive? What general adaptations do invasive species possess?Invasive species have the greatest impact on (small or large?) ecosystems.How do invasive species impact local ecosystems, and what can be done to control their spread and minimize their damage?
- What is a geographic barrier?How do invasive species affect species diversity of communities and ecosystems?Which of the following organisms would be most likely to become invasive if introduced to a new habitat? A- A plant that is pollinated by a single species of insect B- A plant that requires a long period of cold weather in order to germinate C- An animal that reaches sexual maturity at 20 years of age D- A fungus that produces millions of spores that disperse on the wind E- An animal that feeds on only one species of plant
- What should be done about an invasive species, especially one that dominates an ecosystem or causes economic damage? Should we try to eliminate the invasive species entirely? Should we try to contain it or reduce its influence? Should we just give up and learn to live with it?When do invasive species -meditated changes become environmental damage or benefit?what is the difference between negative impacts and significant negative impacts?How does the presence of invasive species affect the ecological interactions and community dynamics within an ecosystem?
