Secondary Consumer - GCSE Biology Definition

A secondary consumer is an animal that eats primary consumers in a food chain. Primary consumers are usually herbivores that feed on producers (plants or algae), while secondary consumers are typically carnivores or omnivores that eat these herbivores. For example, in a woodland ecosystem, a frog is a secondary consumer because it eats insects that feed on plants. Secondary consumers help transfer energy through trophic levels and are an important part of understanding how ecosystems function in GCSE Biology.
