Instructions
- All the questions are compulsory.
- the test is based on the syllabus of Oceanography and Bio-geography.
- Each question carries 10 marks and the word limit is 150.
- The time limit is 1 hour 30 minutes.
- Write your answers and post them.
- Every answer will be evaluated, and feedback will be given.
- Describe the ideal conditions for coral reef formation and threats they are facing.
- Examine economic significance of the resources of the Continental shelf of the Indian Ocean.
- Different layers of ocean water above abyssal plain.
- Illustrate the origin and nature of Sargasso Sea.
- Elucidate how oceans ensures food security.
- Discuss the concept, components and functioning of an ecosystem.
- Uniqueness of fauna in the Notogean realm.
- Give an account of the nature of biosphere as an ecosystem.
- Explain the characteristics of ecological succession.
- Explain the different stages of ecological adaptation of man
Q.1) ideal conditions add these points
-oceanic salinity ranging between 27 ppt to 30 ppt.
– away from coastal areas and river mouths.
add these points to threats
-coral mining
-discharge of industrial effluents, agricultural run-off, urban sewage etc.
-ocean acidifaction leads to shallower depth of Calcite compensation depth (CCD).
Write conclusion.
Q.2) write about ocean energy.
-enrich your answers with facts like Durgaduani Creek, 3.75 MW power plant.
– marine fishing 3rd in Fisheries 2nd in Aquaculture.
each point should be enriched with examples, data or facts.
write conclusion.
model conclusion given below

Q.6) abiotic factors- climatic-examples
edaphic factors-examples.
ecosystem functions
-Energy flow
-Nutrient cycling (biogeochemical cycles)
-Ecological succession or ecosystem development
with examples.
conclusion.
Q.5) use of word biome in the introduction is wrong.
biome means
The term biome means the main groups of plants and animals living in areas of certain climate patterns.
while answering such questions you should first write the need of food security in 2-3 points like
-growing population.
– climate change and decrease in agri output etc.
then should write 6-7 points with data/facts/examples etc.
then conclusion.
Q.9) Succession is characterized by the following:
-increased productivity,
-the shift of nutrients from’ the reservoirs,
-increased diversity of organisms with
-increased niche development,
-and a gradual increase in the complexity of food webs.
also mention the autogenic succession and allogenic succession
then conclude.
Q.4) Mention these points
origin
you forget to mention North Atlantic Drift.
formed due to global wind pattern and Coriolis effect.
nature
-all other seas in the world are defined at least in part by land boundaries, the Sargasso Sea is defined only by ocean currents.
-Since this area is defined by boundary currents, its borders are dynamic.
-exceptionally clear blue and calm waters and visibility up-to 50 meters depth.
-hosts lot of marine life including endangered eels.
conclusion.
