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

The answer is limiting factor

@RJC

ARE U SURE...????
thanks

Oxygen level in water is therefore a limiting factor with respect to the number of trout that a particular stream can support.

To understand why oxygen level is a limiting factor, we need to consider the concept of carrying capacity. Carrying capacity refers to the maximum population size that an ecosystem or habitat can sustain over a long period of time. It is determined by a variety of factors, including food availability, water quality, predation, and the availability of suitable habitat.

In the case of trout in a stream, oxygen is crucial for their survival, as they obtain oxygen through their gills. If the oxygen levels in the water decrease due to changing conditions, such as pollution or reduced water flow, it becomes more challenging for trout to extract enough oxygen to support their metabolic needs. This decrease in oxygen availability can lead to physiological stress and even mortality.

Therefore, when the oxygen levels in the stream decrease, the carrying capacity of the stream for trout will also decrease. This means that the stream will be able to support fewer trout due to the limited availability of oxygen. In other words, oxygen level in water acts as a limiting factor that restricts the number of trout that a particular stream can support.
