Ecology

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 considered 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.
