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.

answer the following questions. Do not pick an organism that is of least
concern.

Type
all answers directly on the data sheet.
