Why do we celebrate water day every year?

  1. We celebrate water day every year to attract the attention of everybody towards the importance of conserving water.

  2. It is a tradition.

  3. It is for commercial purposes.

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer

  1. Composting toilets

  2. Rainwater harvesting

  3. Automatic faucet

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water-saving technology for the home includes:

  • Low-flush toilets and composting toilets. These have a dramatic impact in the developed world, as conventional western toilets use large volumes of water. 
  • Rainwater harvesting high-efficiency clothes washers weather-based irrigation controllers garden hose nozzles that shut off water when it is not being used, instead of letting a hose run. Low flow taps in wash basins. 
  • Automatic faucet is a water conservation faucet that eliminates water waste at the faucet. It automates the use of faucets without the use of hands.

How do you conserve water by watering plants?

  1. By watering optimum quantities regularly

  2. By watering heavily but less often

  3. By watering Twice a week

  4. By watering very little
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Water heavily may  result in root rot due to water logging preventing the roots from respiring aerobically. When roots respire anerobically alcohol produced as a byproduct results in root rot. Watering has to be done based on the season and the water requirement of the plant

So, the correct answer is 'By watering optimum quantities regularly'
