Secondary Consumers / Carnivores (Trophic Level 3). Tertiary Consumers / Carnivores (Trophic Level 4). 2. Energy Transfer Between Trophic Levels How energy is lost moving up the food chain. The 10% rule for energy transfer efficiency. Explanation for the limited length of food chains. 3. Specific Roles in Ecosystems Apex Predators at the top of the food chain. Omnivores and their position in trophic levels. Decomposers and Detritivores role in nutrient recycling. ** EXAM BOARD INFO ** AQA - Separate/triple science only IGCSE Edexcel - Everything is relevant to your course!
