Name the organisms due to which the ponds often look green in colour? What is the source for  growth of such organisms?

Expert Answer:

The green colour is because of algae which is produced in the pond's water. The deposition of algae is caused by excessive quantities of chemicals which get washed from the fields in the rivers or ponds. These act as nutrients for algae to flourish.
