प्रश्न
Explain, why do aquatic animals prefer to stay at lower level of water during summer?
Advertisements
उत्तर
Solubility of gases decreases with increasing temperature. During the summer, the concentration of dissolved oxygen is low at the upper level of water; therefore, aquatic animals prefer to stay at the lower level of water during summer.
