GCSE Biology - Trophic Levels - Producers, Consumers, Herbivores & Carnivores #86

The video explains the concept of trophic levels in a food chain, starting with producers like plants that use photosynthesis to create energy. It describes primary consumers as herbivores, secondary consumers as carnivores, and tertiary consumers as higher-level carnivores. Energy transfer between these levels is inefficient, with only about 10% passing to the next level. Apex predators sit at the top of the chain. Omnivores, which consume both plants and animals, and decomposers, which recycle nutrients, are also discussed.

Define apex predators and their significance in a food chain.

How do decomposers contribute to the ecosystem?
