A secondary consumer in a food web is the carnivorous or omnivorous animal that feeds on the primary consumer, which is the organism (normally a rat) that eats the producer (normally a plant).
In any food chain autotrophs are the producers which synthesizes food using solar energy. Autotrophs are green plants in terrestrial ecosystem. The herbivores which feed on plants are primary consumers and animals which feeds on herbivores are secondary consumer. These are carnivores or omnivores. For example, in forest ecosystem, trees are producers, deer is an primary consumer and lion is secondary or top consumer.
