How are abiotic and biotic factors affect the stream?

Abiotic and Biotic Factors. Water temperature has direct and indirect effects on all aspects of the stream. The concentration of oxygen are governed by temperature. In lower temperature the water holds more oxygen than in high temperature, as a result certain species of aquatic invertebrates and fish will be affected and die.
