Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Hydroponics requires less water than irrigation on agricultural lands.

It is a quicker and a safer as well as productive method.
The disadvantage is that it is an expensive project which requires proper conditions and large investment.
So the correct answer 'Expensive'.

Multiple choice botany mineral nutrition in plants hydroponics hydroculture essential and non-essential mineral elements nutrients and nutrition

Hydroponic requires

  1. 1/10 of water.

  2. 1/35 of water.

  3. 1/55 of water.

  4. 1/5 of water.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Hydroponics requires 10 times less water than normal agricultural plants that require proper methods of watering. A lot of water gets evaporated from the soil or seeps deep inside the layers. But in hydroponics water requirement is just 1/10 of water requirements of traditional agriculture.

So the correct answer is ' 1/10 of water'.

Multiple choice biology wastewater story sewage treatment wastewater treatment - need and methods conservation

The soil pores block and become ineffective in filtering the water due to 

  1. Disposal of oil in drainage pipe.

  2. Disposal of oil in open drain.

  3. Disposal of oil in garden.

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

Oil and fats can clog the drains reducing its effectiveness in filtering water. In open drains, they block the pores in the soil and thus hamper the filtration by soil. Hence, oil and fats should not be released into the drain.

So, the correct answer is 'Disposal of oil in open drain'.

Multiple choice biology wastewater story sewage treatment wastewater treatment - need and methods conservation

Drains get blocked by 

  1. Oil and tea leaves.

  2. Oil and chemicals.

  3. Chemicals and soil.

  4. Chemicals and water.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Cooking oil and fats should not be thrown down the drain. They can harden and block the pipes. In an open drain, the fats clog the soil pores reducing its effectiveness in filtering water. Throw oil and fats in the dustbin. Chemicals like paints, solvents, insecticides, motor oil, medicines may kill microbes that help purify water. So do not throw them down the drain.


So, the correct answer is ''Oil and chemicals.

Multiple choice management of water uses and limitations of dams air, water and soil management of natural resources biology

Check dams are build along seasonal flooded gullies for water harvesting.

  1. True

  2. False

  3. Nither

  4. Either
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
A check dam is a small dam which may be temporarily or permanently constructed across a gully, a draining ditch or channel so as to slow down the speed of concentrated flows. These dams are made for harvesting water and preserving natural water of rain. Hence, these dams are made in seasonal times generally when there is heavy rainfall. The stored water then can be used for various purposes.
Hence, the statement given in the question is correct.
So, the correct answer is 'True'.
