AS Marine Science: Ecosystems and Biodiversity

Section 2: Marine Ecosystems and Biodiversity

Complete lessons covering the following points:

• The meaning of the terms: ecosystem, habitat, population, community, species, biodiversity and ecological niche
• Describing interrelationships within marine ecosystems to include mutualism and parasitism
• explain the meaning of the term: producer, comsumer, predator, prey and trophic level in context of food chains and food webs
• explain how populations of predator and prey may be interrelated

Each powerpoint has talking points, small activities for students (individually or in pairs), video resources and exam questions.

I have also used these for students studying at home.
