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

Water harvesting systems provide versatile benefits, including recharging groundwater, providing water for irrigation, and supplying domestic needs.

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

All of the following are advantages of dams except

  1. flood control

  2. recreation

  3. hydroelectric power

  4. enhancing natural spawning patterns of fish
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

While dams offer benefits like flood control and power generation, they often disrupt aquatic ecosystems and block the natural migration and spawning patterns of fish.

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

It is important to make small check dams across the flooded gullies because they
(i) Hold water for irrigation
(ii) Hold water and prevent soil erosion
(iii) Recharge ground water
(iv) Hold water permanently

  1. (i) and (iv)

  2. (ii) and (iii)

  3. (iii) and (iv)

  4. (ii) and (iv)

  5. (i), (ii) and (iii)
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

A major portion of water stored behind dams in the world is withdrawn for irrigation that is, evaporation and transpiration needs. Water used in excess of evaporation and transpiration needs appears in the system as surface or groundwater. The total quantum of flow and size and frequency of peak floods in the flood season reduce in the downstream due to a dam, reducing flood hazard due to inundation of land, crop and property. It also reduces congestion of run off in plains and coastal lands. Any soil erosion such as gullies already formed can be tackled by the construction of dams or obstructions. 

Therefore, the correct answer is option E.

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

The drawback of dam is

  1. Block fish migration

  2. Can cause flood on dam side area

  3. Displace local people

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

Large dams are frequently criticized for their negative social and environmental impacts, including blocking fish migration, increasing flood risks in certain areas, and displacing local communities.

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

Making of small check dams across the flooded gullies is important because they

  1. hold water and prevent soil erosion

  2. recharge ground water

  3. help stagnate water

  4. hold water for irrigational purpose
Reveal answer Fill a bubble to check yourself
A,C Correct answer
Explanation

Check dams are small barriers built across gullies to slow down water flow, which helps in retaining water, reducing soil erosion, and facilitating groundwater recharge.

Multiple choice zoology excretion in living organisms excretion - animals human excretory system and products excretory system and products excretion - plants excretion in plants

Animals return water to the environment by
(i) Perspiring
(ii) Drinking
(iii) Urinating
(iv) Breathing

  1. (i), (iii) and (iv)

  2. (i) and (ii)

  3. (i) and (iii)

  4. (iii) and (iv)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A) Perspiration (sweating) is the loss of water and salts through the surface of the skin. This water evaporates. Urine is mostly water and is also composed of salts and is excreted by the animal into the environment. While breathing, minute molecules of water or water vapour are given out into the environment along with carbon dioxide.

B) While drinking water, the animal consumes it from the environment.
C) Perspiration and urination release water into the environment.
D) Breathing releases water in form of water vapour into the environment.
So, the correct answer is '(i), (iii) and (iv)'.

Multiple choice basics of management of water environmental science conservation of resources food production: soil and water management biology

Identify the correct statements:
A. Water shed management helps in scientific soil and water conservation.
B. Water harvesting techniques are locally specific and locally benefited.
C. Check dams are practised for the conservation pf seasonally flooded gullies.
D. Groundwater storage techniques are more effective than open-air storage of water.

  1. A, B, C and D

  2. A, C and D

  3. B, C and D

  4. A, B and D
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Water-shed management is the system in which soil and water are conserved by scientific means. Water harvesting techniques help people obtain optimum amounts of water. Check Dams help in collecting water at specific regions and prevent floods. Storage of water below the soil level helps in conservation of water in a better manner. 

So, all the given statements are true. The correct option is "A". 

Multiple choice basics of management of water environmental science conservation of resources food production: soil and water management biology

It is necessary to conserve wetland because

  1. It purify surface water

  2. It recharge ground water

  3. It holds back water

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The wetlands are responsible for the trapping of the chemicals and harmful wastes. This results in protection of the aquatic systems. This also helps to purify the water since the sediments and the waste is trapped in these regions. This protects the groundwater. The activity of the organisms in these regions allows recharging the surface and groundwater. 

Thus, the correct answer is option D. 

Multiple choice basics of management of water environmental science conservation of resources food production: soil and water management biology

Watershed is

  1. An area that contains streams and rivers that drain into the single large water body.

  2. An area that preserves natural water to recharge zones.

  3. An area that catches rain water.

  4. Both A and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

An area or ridge of land that separates water flowing to different rivers, basins or seas is called as watershed. Much of the water comes from rainfall and storm water runoff. Watersheds are usually separated from other watersheds by naturally elevated areas.

Thus, the correct answer is option D.

Multiple choice basics of management of water environmental science conservation of resources food production: soil and water management biology

To protect an area where water is at the surface of earth is the aim of

  1. Watershed conservation

  2. Wetland conservation

  3. Domestic conservation

  4. Industrial conservation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Wetlands are areas where water covers the soil or is present at or near the surface of the earth, and their conservation is specifically aimed at protecting these ecosystems.
