Homework+Due+Tuesday+the+18th+Sept

The following questions are from past HSC papers. As they are all quite similar, you need to anticipate that a similar question will be asked in this years HSC exam. It is important to prepare answers in terms of their structure and examples used. For each of the below questions scaffold an answer. I don’t want you to write an answer but I want you to **scaffold** your answer. I will show you with the 2011 question. I have just done a basic scaffold but expect you to expand on my points. Please hand in bits of paper answering one question per page

Outcompete native fish Increase water turbidity which reduces sunlight effecting the growth of aquatic plants Effect nutrient levels || Shellfish (pacific sea star in ballast water) || Outcompetes native species ||
 * __Accidentally introduced__
