What could be the possible consequence if Water Hyacinth grows too quickly in a pond?

Question

A. Plants like Lotus and Lily would grow rapidly and will eventually increase in number

B. Plants like Hydrilla and Tape Grass would not grow and will eventually die.

C. Plants like Wolfia and Pistia would show reduced growth as Water Hyacinth will occupy a large surface area of pond

D. Both B and C

Answer 1

Both B and C are possibilities, because fast growth would mean it occupies a large area of pond, would rapidly increase herbivores that would eat other weakened plants' and would consume most nutrients in pond.
