Which of the following is not found in polluted water?

biology option c: ecology and conservation hotspots and methods of conservation biodiversity: conservation conservation of biodiversity

  1. Blue green algae

  2. Larvae of stone fly

  3. Water hyacinth

  4. Sewage fungi

Show answer
Correct Option: B
Explanation:
Stoneflies are found in clean and cool flowing streams. They spend most part of their life in the larval form and are sensitive to water pollution. In particular, stoneflies are sensitive to changes in dissolved oxygen and water temperature. They need a high amount of dissolved oxygen to live comfortably. When the dissolved oxygen falls or the temperatures rise and stoneflies disappear. The presence of stoneflies is a reliable indicator of excellent water quality
So, the correct answer is 'Larvae of stone fly'

Which among the following in excess quantity indicates the contamination of Ganga water bodies?

biology option c: ecology and conservation hotspots and methods of conservation biodiversity: conservation conservation of biodiversity

  1. Dissolved minerals

  2. Coliform bacteria

  3. Dissolved carbon

  4. Dissolved phosphates

Show answer
Correct Option: B
Explanation:

A lot of pathogens are present in water bodies that are contaminated. One of these pathogens is coliform bacteria. This bacteria, like other pathogens, is an indicator of contamination in water bodies. This is because it has a similar reaction to purification and water treatment like other pathogens.

So, it can be used as an indicator of water contamination. So, option B is the correct answer.

$S{O} _{2}$ pollution is indicated by

biology option c: ecology and conservation hotspots and methods of conservation biodiversity: conservation conservation of biodiversity

  1. Desmodium (grasses)

  2. Sphagnum (mosses)

  3. Usnea (lichens)

  4. Cucurbita (climbers)

Show answer
Correct Option: C
Explanation:

SO$ _2$ is produced during combustion of fossil fuels, refining of petroleum, smelting of sulphur containing ores, smog and acid rain. SO$ _2$ causes membrane damage, destruction of chlorophyll, necrosis and water soaked appearance. Lichens are the most sensitive organisms to SO$ _2$ pollution and do not grow in areas with high levels of sulphur dioxides. Hence, the correct answer is option C.
