1.	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» 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.
