If changing conditions lead to decreased oxygen levels in the stream, the carrying capacity of the stream for the trout will decrease. Oxygen level in water is therefore a(n) _____________ with respect to the number of trout that a particular stream can support.

Is it "Independent Variable"?

I think it would be "limiting factor"

ill check

No, the term "Independent Variable" refers to the variable that is deliberately changed or manipulated in an experiment. In this case, the changing conditions leading to decreased oxygen levels in the stream are affecting the carrying capacity of the stream for trout.

To determine the correct term for the oxygen level in water with respect to the number of trout a stream can support, we need to consider the relationship between the two variables.

Carrying capacity refers to the maximum number of individuals or species that an environment can support sustainably. In this case, if changing conditions lead to decreased oxygen levels in the stream, it would reduce the carrying capacity for trout.

Therefore, the term that best describes the relationship between oxygen level in the water and the number of trout a particular stream can support is a "dependent variable." The dependent variable is the variable that changes in response to the independent variable, which in this case is the changing oxygen levels.
