  1. A-$4$, B-$1$, C-$3$, D-$2$

  2. A-$4$, B-$2$, C-$1$, D-$3$

  3. A-$2$, B-$3$, C-$4$, D-$1$

  4. A-$2$, B-$1$, C-$4$, D-$2$


Correct Option: A

Which of the following is an ecosystem service provided by a natural ecosystem?

  1. Cycling of nutrients

  2. Prevention of soil erosion

  3. Pollutant absorption and reduction of the threat of global warming

  4. All of the above


Correct Option: D
Explanation:

The products of ecosystem processes which have environmental aesthetic and indirect economic value are named as ecosystem services. Soil formation and soil protection are the major ecosystem services accounting for nearly 50% of their total worth. Plant cover protects the soil from drastic changes in temperature. There is little wind or water erosion as soil particles are not exposed to them. The soil remains spongy and fertile. There are no landslides and no floods. The plant cover of natural ecosystem absorbs polluting gases, causes settling of suspended particulate matter, removes CO2 and releases O2. Purified air becomes available. There is no overall depletion of nutrients as the same as repeatedly circulated and recirculated. This keeps the fertility of soil intact.

So, the correct answer 'All of the above'.

If the average temperature of the sun increased, the wavelength of peak solar emission would:

  1. Shift to a shorter wavelength

  2. Shift to a longer wavelength

  3. Remain the same

  4. Impossible to tell from given information


Correct Option: A

The minimum temperature in the sea is .......... , while in freshwater ponds it never goes below ..........

  1. -3$^o$C, 0$^o$C

  2. -10$^o$C, -4$^o$C

  3. 20$^o$C, -10$^o$C

  4. 25$^o$C, -100$^o$C


Correct Option: A
Explanation:

The temperature of the surface waters varies mainly with latitude. The polar seas (high latitude) can be as cold as -2 degrees Celsius (28.4 degrees Fahrenheit), while the Persian Gulf (low latitude) can be as warm as 36 degrees Celsius (96.8 degrees Fahrenheit).
Temperature varies in ponds and lakes seasonally. During the summer, the temperature can range from $4^0$C near the bottom to $22^0$C at the top. During the winter, the temperature at the bottom can be $4^0$C, while the top is $0^0$C (ice).

Thus, the correct answer is option A.

  4. June 22; December 22


Correct Option: C
