Questions Related to climate factors

Due to the increased average global temperature on fish populations, the fish will show
I. Movement from saline to fresh waters
II. Movement to deeper waters
III. Movement to higher latitudes

  1. I only

  2. II only

  3. III only

  4. I and II

  5. II and III

Show answer
Correct Option: E
Explanation:

Limited or no sunlight in deeper waters keep the temperature lower in the regions making it suitable for fishes when surface water become warm due to increasing in average global temperature. Likewise, higher latitudes maintain lower temperatures due to the angle of irradiance. Salinity does not affect the temperature range of water bodies. Thus, the correct answer is E.

There is no atmospheric reservoir in

  1. Carbon cycle

  2. Water cycle

  3. Phosphorus cycle

  4. Sulphur cycle

Show answer
Correct Option: C
Explanation:

The abiotic components which are recycled without any involvement of the gaseous form are known as the sedimentary cycle. The element is present in the form of salts as rocks in the geosphere which is taken up by the plants and then transferred to the animals. The phosphate is generally transferred and used in the form of ATP by the living cells. There is no form of phosphorus present in the atmosphere.

Thus, the correct answer is option C. 

The phosphorus cycle differs from those of carbon and nitrogen as well as from those of sulphur, oxygen and hydrogen in that it lacks

  1. Water

  2. Dust particles

  3. Gaseous phase

  4. All of the above

Show answer
Correct Option: C
Explanation:

The abiotic components which are recycled without any involvement of the gaseous form are known as the sedimentary cycle. The element is present in the form of salts as rocks in the geosphere which is taken up by the plants and then transferred to the animals. The phosphate is generally transferred and used in the form of ATP by the living cells. The remaining abiotic components including sulphur, carbon, oxygen and hydrogen. 

Thus, the correct answer is option C.

  1. All birds and mammals are capable of thermoregulation

  2. Majority of animals and nearly all plants cannot maintain a constant internal environment

  3. Shivering is a kind of exercise which produces heat and raises body temperature

  4. Very small animals are commonly found in polar regions as they have to spend less energy to generate heat

  5. Diapause is a stage of suspended development seen in zooplankton

Correct Option: D

Select incorrect statement :

  1. Orchid epiphytic on Mango is commensal

  2. Bird laying eggs in the nest of another for incubation shows brood parasitism

  3. Most animals and plants maintain a constant internal temperature

  4. Small animals are rare in polar regions

  5. One species harmed, other unaffected in amensalism

Correct Option: C

The lowest temperature of any land mass of the universe was recorded in

zoology environmental factors soil-nature climate factors abiotic components organisms and environment

  1. North America (1949)

  2. Mt. Everest, Himalayas (1954)

  3. Antarctica (1982)

  4. Siberia (1947)

Show answer
Correct Option: D
Explanation:

The Siberian city of Yakutsk is the coldest in the world. It was -89.8$^0$C temperature in 1947. Coldest Temperature in North America was -62.8$^0$C in 1949. The temperature of Mt. Everest, Himalayas in 1954 was -36$^0$C. Antarctica's lowest temperature was recorded in 1982 and was -89.2$^0$C. 

Thus, the correct answer is option D.

State whether the following statements are true or false.
Generally,a larger human population could be maintained on the same amount of cultivated
land if people ate more plants rather than animals

botany environmental factors soil-nature climate factors abiotic components

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

A larger human population can't be maintained on the same amount of cultivated land because after 2-3 yields of any crop the soil generally loses its fertility. Therefore, other lands have to be cultivated. So the correct option is "False".

Which one of the following is not a correct match of the term and its description?

zoology environmental factors soil-nature climate factors abiotic components organisms and environment

  1. Ecosystem - Functional unit of nature

  2. Global ecosystem - Entire biosphere

  3. Aquatic ecosystem - Wetland

  4. Natural ecosystem - Crop field

Show answer
Correct Option: D
Explanation:

Crop field is considered as man-made(anthropogenic or artificial) ecosystem. Natural ecosystem is developed in nature without human involvement, e.g., forest, ocean, etc.

The abiotic components of the environment are the living factors.

zoology environmental factors soil-nature climate factors abiotic components organisms and environment

  1. True

  2. False

Show answer
Correct Option: B
Explanation:
There are two major components of an ecosystem:
  • Abiotic components: These are non living components of environment and consist of two things, materials and energy (that may be light or chemical energy). Materials include water, minerals, salts, atmospheric gases etc.
  • Biotic components: These are living components of environment and divided into autotrophic and heterotrophic components. Autotrophic component is the producers or green plants while heterotrophic component includes consumers (primary, secondary and tertiary consumers) and decomposers.
Hence, the statement given in the question is incorrect.
So, the correct answer is 'False'.
