Multiple choice biology improvement in food resources manure manures and fertilisers role of organic manures in soil management

The first effect of adding fertiliser to a pond would most likely be to________

  1. Decrease the amount of phytoplankton

  2. Kill most bacteria

  3. Lower the compensation point

  4. Increase the amount of phytoplankton
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • The fertilizers are the rich source of nitrogen and phosphorous used for the growth of plants.
  •  When the fertilizers are introduced in the pond, these nutrients increase the fertility of the pond. 
  • The phytoplanktons are the autotrophic organisms in the aquatic environment that utilize these nutrients and increase in the number. 
Thus, the correct answer is option D.

Apart from soil fertility, manure also enhances .......... of the soil. 

  1. Decomposition of microorganisms

  2. Roots holding capacity

  3. Soil binding capacity

  4. Water holding capacity

D Correct answer
Explanation
  • Manure is an organic substance produced by the decomposition of plant and animal wastes in the presence of microorganisms and used as fertilizers. It enhances the water holding capacity of the soil. 
  • It also makes the soil porous which makes the exchange of gases easy.

Therefore, the correct answer is option D.

  2. Manure

  3. Water

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

Manure is organic and provides nutrients slowly, often leading to a more gradual increase in crop productivity compared to chemical fertilizers. Fertilizers are typically designed for more rapid and significant yield increases.

  2. Phosphorous

  3. Potassium

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

  • Fertilizers, the chemically synthesized substances which are very rich in the plant nutrients like nitrogen, phosphorous and potassium.
  • Nitrogen (N) required for the leaf growth 
  • Phosphorus (P) required for the development of roots, flowers, seeds, and fruit 
  • Potassium (K) required for strong stem growth, movement of water in plants, promotion of flowering and fruiting. 

Therefore, the correct answer is option D.

Animal manure can be contaminated due to

  1. Paper

  2. Wool

  3. Stones

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

Animal manure is organic matter, which is used as a fertilizer in agriculture. The manure gets contaminated only when micro-organisms attack. Animal manure can improve the soil aggregation so that the soil becomes more fertile. Horse manure is mostly used in agriculture apart from the horse manure cattle manures like cow dung, sheep manure.

So, the correct option is ' None of the above'.

  1. Stored

  2. Old

  3. Fresh

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

  • Manure is an organic substance produced by the decomposition of plant and animal wastes in the presence of microorganisms and used as fertilizers. Fresh manure has microbes in it, that may be dangerous. It should not be applied to edible crops that will soon be harvested. Instead of fresh manure aged or old manure should be applied to the edible crops.

Therefore, the correct answer is option C.
