C Correct answer
Explanation

The aquatic ecosystem is the interaction of biotic component and abiotic component in the water body. It serves important environmental services such as recycling of nutrients, water purification, attenuate floods, recharge groundwater and provides shelter to wildlife. Aquatic ecosystems are also used for human recreation, and are very important to the tourism industry, especially in coastal regions.

Which features are characteristic of insect-pollinated flowers?

  1. Bright petals, large feathery stigmas

  2. Bright petals, rough sticky pollen

  3. Large feathery stigmas, nectaries

  4. Small light pollen, nectarines
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Insect-pollinated flowers are large, have brightly coloured petals, often sweetly scented, usually contain nectar- to attract insects. Its pollen are often sticky or spiky - to stick to legs and body of  insects

So, the correct is 'bright petals, rough sticky pollen'

Mid latitude lakes undergo mixing more than equatorial lakes, select the correct reason.

  1. The midlatitude lakes turn over twice a year

  2. Midlatitude lakes develop a thermocline
  3. Water is densest at $4$

  4. All of the above

  5. They don't - equatorial lakes have more mixing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Deep lakes at mid-latitudes have well-pronounced stratification which leads to the lakes experiencing wealthy internal waves dynamics. These lakes also possess seasonal water mixing during the spring and autumn transitional periods. This is due to the non-linear thermal expansion of water when its temperature reaches 4$^0$C and the density of water is maximum.  Further, with the increasing latitudes support the general cyclonic water circulation. Hence the large lakes along mid-latitudes show a large variety of these physical processes.

Identify the correct statement for freshwater ecosystems.
I. There is a seasonal mixing of materials.
II. During the year, oxygen concentrations are vertically uniform.
III. Materials are recycled more quickly than in ocean ecosystems.

  1. I only

  2. II only

  3. III only

  4. I and III

  5. II and III

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

A Freshwater ecosystem is one of  the aquatic ecosystems of the earth and includes lakes, ponds, rivers, streams and wetlands. This ecosystem is essential as it not only provides human beings their drinking water, but these are also home to more than 40 percent of the world's fish species. The seasonal changes occur in the freshwater ecosystem with regards to temperature-density relationship and since it contains continuous running water so materials are recycled more quickly than in ocean ecosystems.

So, the correct answer is option D.

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

Robert Constanga et al have tried to put price tags on natures life support services. He gave price tags to the ecosystem services. Out of these services, 50% accounts for the soil formation. The ecosystem services he put price on includes purify water and air, mitigate droughts and floods, nutrient cycling, habitat for wild life.

Thus, the correct answer is 'Robert Constanga et al.'
