B4 Competition and interdependence

There is a lot of biological concepts to cover in this lesson (my advice would be to do Task 3 (research task) in a separate lesson and finish that lesson with some past exam questions. The biggest mistake teachers make here is they fly through this section and students mis the understanding of key terms like bioaccumulation and the examboard loves to test students scientific knowledge on the concepts covered in this lesson

This lesson covers

• the term competition - students can watch a short clip on intrasepecfic competition
• terms - predation, mutualistic and parasitism relationships explained and questions to consolidate students learning
• term bioaccumulation explained
• independent research task
