Question

In a pond where water hyacinths are found to be flourishing,it is observed that submerged water plants could barely survive. What could be the possible explanation for the observation.​

Answer 1

Explanation:

Water hyacinth (Eichhornia crassipes) is a large aquatic plant native to the Amazon basin. Its thick, waxy, oval-shaped leaves are 4-8 inches across and branch out from the center of the plant on modified stems that may rise as much as 1 meter above the water surface. The mass of fine roots that hang in the water underneath the plant are dark purple or black with small, white root-hairs. The stems are spongy, bulbous stalks (called petioles) that contain air-filled tissues that keep the plant afloat. When flowering, the stalks support 8 – 15 blue-violet flowers with six petals each, with one petal being deeper violet with a yellow spot.
