1. Question
Regarding the influence of the number of Ecotones on the ecosystem, which of the following statements is/are accurate?
(1) More Ecotones result in a greater number of eco transition zones.
(2) More Ecotones lead to greater species diversity.CorrectCorrect Answer: C
Explanation: A more diverse ecosystem tends to be more stable. Higher species diversity and inter-dependence are observed with more Ecotones due to the presence of various transition zones like ponds and grasslands. Furthermore, a smaller number of dominating species promotes even greater ecosystem diversity.

2. Question
What are the primary factors determining the speed of organic matter decomposition?
(1) Soil organisms
(2) Temperature conditions
(3) Moisture conditions
(4) Quality of the organic matterCorrectCorrect Answer: D
Justification: Decomposition is predominantly a biological process that occurs naturally. High temperatures and moisture levels facilitate decomposition. During this process, various products are released, including carbon dioxide (CO2), energy, water, plant nutrients, and resynthesized organic carbon compounds.

3. Question
Which of the following materials are non-biodegradable?
1) Cotton cloth
2) Ball-point pen refills
3) Glass objects
4) Silver FoilCorrectCorrect Answer: C
Explanation: Non-biodegradable waste refers to materials that cannot be broken down into harmless substances by natural processes. Examples include plastics, polythene bags, ball-point pen refills, synthetic fibers, glass objects, and metals like aluminum cans, iron nails, and silver foil. In contrast, biodegradable waste includes materials like cotton cloth, paper, woolen clothes, and wood.

4. Question
The ‘Ecosystem approach’ is based 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: According to the Conference of the Parties to the CBD, the ecosystem approach is the primary framework for action under the Convention. An ecosystem is defined as 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, emphasizing appropriate scientific methodologies focused on biological organization levels that encompass the essential processes, functions, and interactions among organisms and their environment. This approach recognizes humans, with their cultural diversity, as integral components of ecosystems.
