Step-by-step explanation:

Mayflies would be considered as indicator species in this context. Indicator species are organisms that are sensitive to changes in their environment or specific ecological conditions. They can provide insights into the health and quality of an ecosystem. In the given scenario, if mayflies are present in a stream, it indicates that the stream is likely to be healthy because mayflies are sensitive to pollution or low dissolved oxygen levels. Their presence suggests that the stream has adequate water quality and oxygen levels to support their survival.
