How did the Mono Lake problem arise?
The Mono Lake problem arose due to excessive water diversions by the Los Angeles Department of Water and Power in the 20th century, which caused a significant drop in the lake's water levels. This led to ecological imbalances, including the decline of the lake's ecosystem and habitat for migratory birds. Environmentalists and scientists raised concerns about the impact of these water diversions on Mono Lake's health.
Which two examples of organisms interacting with abiotic factors in the mono lake?
Two biotic interactions that take place in the Mono Lake ecosystem are shrimp eating microscopic algae and the birds eating the flies in the Mono Lake.
What is the major limiting factor in Mono Lake algae that effects everything else?
The major limiting factor in Mono Lake algae is phosphorus availability. Phosphorus is essential for algae growth, and the low levels of phosphorus in Mono Lake limit the algal population, which in turn affects the entire ecosystem as algae form the base of the food web.
Why does mono lake have a high pH and salt concentration?
Mono Lake has a high pH and salt concentration due to its unique geographic location. It is a terminal lake with no outlets, leading to the accumulation of salts and minerals over time. Additionally, the lake's watershed is composed of volcanic rocks that contribute alkaline substances, further raising the pH levels.
What salts and other elements are found dissolved in the mono lake?
Mono Lake contains high concentrations of salts like sodium chloride, sodium carbonate, and various trace minerals such as boron, arsenic, and lithium. These elements are dissolved in the lake due to the high evaporation rates and limited freshwater inflow, resulting in a highly alkaline and saline water body.
