Populations and Communities

Welcome to Populations and Communities

This unit is all about how population sizes is nature find equilibrium, and what things occur to disrupt this equilibrium. You will also learn how to analyze populations.

Follow the directions in each of the lessons in the table of contents. Do everything listed on each page as doing it all will help you learn the information well. If you do the minimum through these lessons you'll find much difficulty through this course.

Each lesson may have a video, a practice worksheet, a quiz, activity etc. and they are all there to help you understand the information better. If you see something highlighted in blue, it is a hyperlink for you to click. If you see something highlighted in green, it is also a link to click and it is an assignment/quiz which will be for marks.

Review - Populations and Communities

You've now finished learning through the final unit of this course. There are only a couple of other matters to attend to before you're completely finished. On this page there will be some review information to help you prepare for the populations quiz, the unit D test, and the diploma exam.

1. Here is a notes package with information covering what you learned about this unit.

2. Here is the main concept study guide. With this document you should be able to look at any of the points here and explain in detail the structure/function etc. without looking at your notes. That will show you that you understand this information and are ready to proceed.

3. Write the final quiz of this course, the populations quiz. Once done, contact your teacher to plan a time for you to write the unit D test. 

Hoorah, you're in the homestretch. All that is left in this course is to study, study, study! make sure to contact your teacher if there are any questions or concerns in order to get them straightened out right away.
