Is a shrew a tertiary consumer?

A shrew is not typically classified as a tertiary consumer; it is usually considered a primary or secondary consumer. Shrews primarily feed on insects, worms, and other small invertebrates, placing them in the role of secondary consumers in many ecosystems. Tertiary consumers are generally larger predators that feed on primary and secondary consumers. Therefore, while shrews play a significant role in their food webs, they do not fit the definition of tertiary consumers.
