ग्रहों की स्थिति

Q1. दूरी के अनुसार ग्रहों की स्थिति ? बुध (Mercury) शुक्र (Venus) पृथ्वी (Earth) मंगल (Mars) वृहस्पति (Jupiter) शनि (Saturn) यूरेनस (Uranus)...

● Water hyacinth is a free-floating and flowering invasive aquatic plant that originated from Amazon Basin, South America.

● It grows rapidly and can form thick layers over the water. So Water hyacinth is considered invasive throughout the world.

● These mats shade out the other aquatic plants. Eventually, these shaded plants die and decay.

● The decaying process depletes the amount of dissolved oxygen in the water. As oxygen levels decline, many fish are unable to survive.
Hence, often the waters below water hyacinth masses witness the absence of life.

Other Effects of Water Hyacinth:

● It interferes with boat navigation and prevents fishing, swimming and other recreational activities.

● It may also clog intake pipes used for drinking water, hydropower or irrigation.

● It creates a prime habitat for mosquitoes that carry a variety of infectious diseases. So, water hyacinth is also considered a serious threat to biodiversity and human health.

Water Hyacinth in India:
● States like Assam and Kerala are highly affected by the Water Hyacinth.
Water Hyacinth is also referred to as the Bengal terror. This is because of its effect on the local ecology and lives of the people.
