Which statements describe turbidity? Check all that apply. This is the paragraph:

Turbidity is a term used to describe water clarity, or how clear the water is. Cloudy water is said to be turbid. Turbid water may be a result of a buildup of sediments, which are pieces of rocks that have been broken down and eroded or transported by surface runoff. Human activities that remove plants in an area may increase erosion. Sediments can get into the gills of fish, which can then decrease their growth and delay development. Sediments prevent sunlight from reaching the producers of the aquatic ecosystem, such as algae. This, in turn, affects the food webs in this ecosystem.
