Explanation

The aquatic plant 'water hyacinth' is one of the most invsive weeds found growing wherever there is standing water. It drains oxygen from the water, which leads to death of other aquatic forms of life. It can propagte vegetatively at a phenomenal rate and spread all over the water body in a short period of time, hence it is very difficult to get rid off.
