Trophic Levels: Trophic Levels - Food Chains ⛓️ GCSE Biology Learning & Revision
Description
In this episode, we discuss trophic levels and food chains.
Food chains illustrate the transfer of energy through an ecosystem via feeding relationships.
Each organism occupies a specific trophic level, beginning with producers like plants and progressing through primary, secondary and tertiary consumers.
Predators consume other animals (prey), and apex predators reside at the top of the food chain. At the base of all food chains are producers and the final stop on the chain is the role that decomposers play.
Decomposers recycle organic material by breaking down dead matter, thereby releasing nutrients back into the environment.
