1. Question
If there are more number of Ecotones
(1) There will be more number of eco transition zones
(2) There will be greater species diversityCorrectCorrect Answer: C
A more diverse ecosystem is more stable, remember this as the golden rule.If there is less evenness among species, there will be greater diversity. If there are more number of Ecotones, there will be a lot of transition zones (e.g. ponds, grasslands etc), and there will be greater species diversity and inter-dependence.
Finally, if less number of species dominate, it is good for the ecosystem diversity even more.

2. Question
Decomposition of organic matter Its speed is determined by which of these major factors?
(1) Soil organisms
(2) Temperature conditions
(3) Moisture conditions
(4) Quality of the organic matterCorrectCorrect Answer : D
Justification: It is largely a biological process that occurs naturally. High temperature and high moisture aide the process of decomposition.
In the decomposition process, different products are released: carbon dioxide (CO2), energy, water, plant nutrients and resynthesized organic carbon compounds.IncorrectCorrect Answer : D

3. Question
Which of these are non-biodegradable materials?
1) Cotton cloth
2) Ball-point pen refills
3) Glass objects
4) Silver FoilCorrectCorrect Answer C:
The waste materials which cannot be broken down into non-poisonous or harmless substances in nature are called nonbiodegradable waste. Examples are plastics, polythene bags, ball-point pen refills, synthetic fibers, and glass objects, metal articles like aluminum cans, iron nails, silver foil, and radioactive wastes. Cotton cloth, paper, woolen clothes, wood, etc. are bio-degradableIncorrectCorrect Answer C:

4. Question
Among the following, the largest population is likely to be found in
CorrectCorrect Answer : D
In the diagram below, several levels of the ecosystem have been given.
A biome harbors a large number of species and not a particular species. Some of the major biomes of the world are forest, grassland, desert and tundra biomes.
However, a biosphere is the largest entity that subsumes the ecosystem, biomes, etc.IncorrectCorrect Answer : D

5. Question
The ‘Ecosystem approach’ relies on
(1) Integrated management of land, water, and living resources that promotes conservation and sustainable use in an equitable way
(2) Adopting completely organic and natural methods, bypassing anthropogenic scientific methodologies, focused on levels of biological organization harnessing the mutual synergy
Which of the above is/are correct?CorrectCorrect Answer: A
Justification: As described by the Conference of the Parties to the CBD, the ecosystem approach is the primary framework for action under the Convention. “Ecosystem” means a dynamic complex of plant, animal and microorganism communities and their non-living environment interacting as a functional unit”. It is a holistic approach to conservation. It is based on the application of appropriate scientific methodologies focused on levels of biological organization which encompass the essential processes, functions and interactions among organisms and their environment. It recognizes that humans, with their cultural diversity, are an integral component of ecosystems.IncorrectCorrect Answer: A
