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 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
Answers
Answer:
A
Explanation:
The phosphate ions promote the growth of algae in water
More the algae present, more the surface area of the waterbody covered and oxygen cannot
penetrate into the depth of the water, it is utilized by the algae
As a result, there will be an increased growth of algae and decrease in dissolved oxygen
So, the correct answer is (a)
Answer:
a) decreased level of dissolved oxygen and increased growth of algae
Phosphorus is an essential element for plant life, but when there is too much of it in water, it can speed up eutrophication (a reduction in dissolved oxygen in water bodies caused by an increase of mineral and organic nutrients) of rivers and lakes. Also, Too much phosphorus can cause increased growth of algae and large aquatic plants. High levels of phosphorus can also lead to algae blooms that produce algal toxins which can be harmful to human and animal health.
