Topic 2.1: Species and Populations for IB ESS

Course Slide Deck

File size: 12 mB

The course is designed to support students studying the IB Environmental Systems and Societies course at Diploma Level and supported with over 70 minutes of Video lessons, plus, Interactive activities, Simulations, Quizzes, a Workbook and Sample Exam style questions. The slides used throughout the course are also available to download.

Covering Topic 2.1: Species and populations, where we will look at the concepts of  the species, populations and habitats. We will investigate the relationships between biotic and abiotic factor in the ecosystem as well as build an understanding of the niche and how that is defined by the resources available to each species. We will also examine the interactions involved in competition – predation, herbivory, parasitism, mutualism and disease.

From that foundation we will look at how these interactions describe the development of populations and the limits to population growth as carrying capacity.

The course will also examine how to use descriptive and inferential statistics and draw conclusions about populations. This will help students prepare for the Internal Assessment in Environmental Systems and Societies.

Whilst this course is primarily focused at IB Diploma Environmental Systems and Societies, it is also useful for any High School students doing ecology, geography or environmental science.

The course is built to help students review and prepare for summative assessments in the subject as well as provide additional understanding, examples and ways of thinking about the course.
