Unit V Assessment

 

Introduction

 

In previous chapters, we learned that life is very diverse. Organisms range from single cells to multi-celled. Some organisms cannot even be seen with the naked eye. Is diversity increasing or decreasing? In the future, will we have more organisms? Does our population play a role in the lives of other organisms? Should we be concerned if an organism goes extinct? The following exploratory activity will help you understand threats to organisms, what is being done to save them, and how organisms are classified.

 

Objective

 

1. Subdivide organisms according to taxonomic classification.

2. Evaluate the effects of human habits on ecosystems and organisms.

 

Materials

 

Computer with internet access

 

Directions

 

2. In the Search Term Box, type in your state or a state you are interested in (Alabama, Florida, etc.)

3. Pick one of the organisms from the list, and answer the following questions. Do not pick an organism that is of least concern.

  1. Type all answers directly on the data sheet.
  2. Select Save As, and use your last name and student ID as a file name.
  3. Upload the data sheet as a .doc, .docx, or .rtf file when finished.

Question 21 is an extended response question and should be at least 100 words. Total: 10 points

 

 

 

 

 

 

 

21. Considering what you have learned from this activity and the textbook chapters, explain your thoughts about the following statement.
