Populations in Ecosystems A level Biology

This is a lesson I used myself to teach the Populations in Ecosystems concept of the Inheritance Genetics Inheritance and Populations unit, unit 7. - A level Biology, AQA specification.

Learning objective: To understand how populations interact within ecosystems, including how biotic and abiotic factors, competition, and succession influence population size and species distribution.

By the end of the lesson learners should be able to:

Success criteria:

SC1: I can describe key ecological terms such as population, community, niche and carrying capacity and explain how they are measured through sampling techniques.

SC2: I can analyse how biotic (living) and abiotic (non-living) factors affect population stability, competition, and the process of ecological succession.

SC3: I can evaluate how human activity and conservation strategies influence ecosystem balance and biodiversity over time.
