Place the lentils in a large saucepan; cover with water to 2 inches above lentils, and bring to a boil. Cover, reduce heat, and simmer 20 minutes or until tender. Drain well; add to bulgur, and set aside. Heat 1 tablespoon of olive oil in a large nonstick skillet over medium-high heat.
Turbidity is caused by include organic materials such as algae, and inorganic materials such as silt and sediment. Suspended solids in a body of water are often due to natural causes. These natural solids include organic materials such as algae, and inorganic materials such as silt and sediment.
Thus, the cloudier the water, the greater the turbidity. As algae, sediments, or solid wastes increase in the water, so does turbidity. Turbidity affects organisms that are directly dependent on light, like aquatic plants, because it limits their ability to carry out photosynthesis. This, in turn, affects other organisms that depend on these plants for food and oxygen. Scientists often consider turbidity of the water in connection with other factors to get a better understanding of its causes and consequences.
