High content of phosphate ion in river Yamuna may lead to:
A. decreased level of dissolved oxygen and increased growth of algae
B. decreased level of dissolved oxygen and no effect of the growth of algae
C. increased level of dissolved oxygen and increased growth of algae
D. decreased level of dissolved oxygen and decreased growth of algae
Answer:A
High content of phosphate ion in river Yamuna may lead to:
A. decreased level of dissolved oxygen and increased growth of algae B. decreased level of dissolved oxygen and no effect of the growth of algae C. increased level of dissolved oxygen and increased growth of algae D. decreased level of dissolved oxygen and decreased growth of algae
Explanation: When the amount of phosphate ions in water increases, it leads to decreased level of dissolved oxygen which is harmful for the aquatic organisms. This leads to an increased growth of algae due to presence of nutrients.
