At Mono Lake, a notable tertiary consumer that crossed the land bridge is the California gull (Larus californicus). These birds primarily feed on smaller fish, insects, and other organisms, placing them at the top of the local food web. Their presence in the region is significant, as they help maintain ecological balance by controlling populations of prey species. The California gull is an example of how species adapted to different environments can traverse land bridges to occupy new ecological niches.
Tertiary consumers in a lake ecosystem typically include larger predators that feed on secondary consumers. Examples of these include larger fish species like pike and bass, as well as birds such as herons and waterfowl that prey on smaller fish and amphibians. Additionally, some mammals like otters or raccoons may also act as tertiary consumers by hunting these secondary consumers in the aquatic environment. These organisms play a crucial role in maintaining the balance of the ecosystem by regulating the populations of lower trophic levels.
