DEF

[An animal] in the food chain that consumes herbivores, i.e. carnivores.

CONT

Herbage is said to belong to the class known as producers, which transform solar energy and carbon dioxide into sugars via photosynthesis. The remaining links are consumers. Consumers are ordered first, second, and so on. Thus a three-stage food chain would be grass consumed by cattle consumed by man, i.e. producer, first-order consumer, second-order consumer.

OBS

A carnivore is a second-order consumer.

OBS

Compare with "carnivore".
