A "tápláléklánc" is a sequence that shows how energy and nutrients flow through an ecosystem. It starts with producers, like növények, which create their own food through photosynthesis. These producers are then eaten by primary consumers, such as herbivorok, which are in turn consumed by secondary consumers, like ragadozók. Each link in the chain represents a different level of the food web, illustrating the relationships between organisms. Decomposers, such as gombák and baktériumok, play a crucial role by breaking down dead matter, returning nutrients to the soil and supporting the growth of producers.
