Question 1 of 5
1. Question
Consider the following statements about the application of algae.
- Used to make Biodiesel and Bioethanol.
- It is a complete protein with essential amino acids.
- Used as fertilizers and soil conditioners.
- Used in Wastewater Treatment.
Which of the above statements is/are correct?
Correct
Solution: d)
- Algae can be used to make Biodieseland Bioethanol.
- It is a complete protein with essential amino acids (unlike most plant foods) that are involved in major metabolic processes such as energy and enzyme production.
- They are used as fertilizers, soil conditioners and are a source of livestock feed.
- Algae are used in Wastewater Treatmentfacilities, reducing the need for greater amounts of toxic chemicals than are already used.
- Algae can be used to capture fertilizers in runoff from farms.

Question 2 of 5
2. Question
Which of the following are an ecotone?
- Mangroves
- Grassland
- Forest
- Estuary
- Coral Reef
Select the correct code:
Correct
Solution: b)
An ecotone is a transition area between two biomes. It is where two communities meet and integrate. It may be narrow or wide, and it may be local (the zone between a field and forest) or regional (the transition between forest and grassland ecosystems).
- For e.g. the mangrove forestsrepresent an ecotone between marine and terrestrial ecosystem, grassland (between forest and desert), estuary (between fresh water and salt water) and river bank or marsh land (between dry and wet).

Question 3 of 5
3. Question
Which of the following fall under the category of Primary pollutants?
- Oxides of Sulphur
- Particulate Matter
- POPs (Persistent Organic Pollutants)
- Chlorofluorocarbons
- Ground Level Ozone
Select the correct code.
Correct
Solution: a)
A primary pollutant is an air pollutant emitted directly from a source. They are “directly” emitted from the processes such as fossil fuel consumption, volcanic eruption and factories. The major primary pollutants are Oxides of Sulphur, Oxides of Carbon, Oxides of Nitrogen, Methane, Particulate Matter, Ammonia, Chlorofluorocarbons, Toxic metals etc.
A secondary pollutant is not directly emitted as such, but forms when other pollutants (primary pollutants) react in the atmosphere. Important secondary Air Pollutants are Ground Level Ozone, Smog and POPs (Persistent Organic Pollutants).

Question 5 of 5
5. Question
consider the following statements about ‘Pioneer species’.
- They are the first to colonize previously disrupted or damaged ecosystems.
- They are often photosynthetic plants
- Algae, Mosses and Lichens are the examples of pioneer species.
Which of the above statements is/are correct?
Correct
Solution: d)
Pioneer species are hardy species which are the first to colonize previously disrupted or damaged ecosystems, beginning a chain of ecological succession that ultimately leads to a more biodiverse steady-state ecosystem.
Since some uncolonized land may have thin, poor quality soils with few nutrients, pioneer species are often hardy plants with adaptations such as long roots, root nodes containing nitrogen-fixing bacteria, and leaves that employ transpiration. Note that they are often photosynthetic plants, as no other source of energy (such as other species) except light energy is often available in the early stages of succession, thus making it less likely for a pioneer species to be non-photosynthetic.
Algae, Mosses and Lichens are the examples of pioneer species.
