Here's why:
* Abundant: Brine shrimp are incredibly abundant in Mono Lake, making up a significant portion of the lake's biomass.
* Primary Consumer: They are filter feeders, consuming algae and other microscopic organisms, making them the primary consumers in the ecosystem.
* Food for many: Brine shrimp are a crucial food source for a wide variety of organisms, including:
* Birds: Migratory birds like the California Gull rely heavily on brine shrimp as a food source.
* Fish: The few fish species that can tolerate Mono Lake's high salinity (such as the Tui Chub) feed on brine shrimp.
* Insects: Some aquatic insects also feed on brine shrimp.
While other organisms like algae, bacteria, and insects contribute to the food web, the sheer abundance and importance of brine shrimp as a primary food source make them the cornerstone of the Mono Lake ecosystem.
