Practice Environment as a timed test →- Q1.Biodiversity
From the ecological point of view, which one of the following assumes importance in being a good link between the Eastern Ghats and the Western Ghats?
- a)Sathyamangalam Tiger Reserve
- b)Nallamala Forest
- c)Nagarhole National Park
- d)Seshachalam Biosphere Reserve
Explanation: The Sathyamangalam Tiger Reserve in Tamil Nadu acts as a crucial ecological corridor linking the Eastern Ghats and the Western Ghats, enabling gene flow and movement of wildlife between the two ranges. Hence option (a).
- Q2.Pollution
In the context of solving pollution problems, what is/are the advantage/advantages of bioremediation technique? 1. It is a technique for cleaning up pollution by enhancing the same biodegradation process that occurs in nature. 2. Any contaminant with heavy metals such as cadmium and lead can be readily and completely treated by bioremediation using microorganisms. 3. Genetic engineering can be used to create microorganisms specifically designed for bioremediation. Select the correct answer using the code given below:
- a)1 only
- b)2 and 3 only
- c)1 and 3 only
- d)1, 2 and 3
Explanation: Bioremediation enhances natural biodegradation processes (statement 1 correct), and genetically engineered microorganisms can be designed for it (statement 3 correct). However, heavy metals like cadmium and lead cannot be readily and completely treated by microorganisms, so statement 2 is wrong. Hence 1 and 3 only.
- Q3.Biodiversity
Due to some reasons, if there is a huge fall in the population of species of butterflies, what could be its likely consequence/consequences? 1. Pollination of some plants could be adversely affected. 2. There could be a drastic increase in the fungal infections of some cultivated plants. 3. It could lead to a fall in the population of some species of wasps, spiders and birds. Select the correct answer using the code given below:
- a)1 and 2 only
- b)2 and 3 only
- c)1 and 3 only
- d)1, 2 and 3
Explanation: Butterflies are pollinators, so their decline affects pollination (statement 1). Some plants rely on insect activity to resist or signal infections, and butterfly decline can indirectly increase fungal infections (statement 2). Butterflies and their larvae are prey for wasps, spiders and birds, so their decline reduces these predators (statement 3). All three are likely consequences.
- Q4.Wildlife Conservation
According to the Wildlife (Protection) Act, 1972, which of the following animals cannot be hunted by any person except under some provisions provided by law? 1. Gharial 2. Indian wild ass 3. Wild buffalo. Select the correct answer using the code given below:
- a)1 only
- b)2 and 3 only
- c)1 and 3 only
- d)1, 2 and 3
Explanation: The Gharial, Indian wild ass, and wild buffalo are all listed in Schedule I of the Wildlife (Protection) Act, 1972, giving them the highest protection so that they cannot be hunted except under specific legal provisions. Hence 1, 2 and 3.
- Q5.Climate Change
With reference to 'Global Climate Change Alliance', which of the following statements is/are correct? 1. It is an initiative of the European Union. 2. It provides technical and financial support to targeted developing countries to integrate climate change into their development policies and budgets. 3. It is coordinated by World Resources Institute (WRI) and World Business Council for Sustainable Development (WBCSD). Select the correct answer using the code given below:
- a)1 and 2 only
- b)3 only
- c)2 and 3 only
- d)1, 2 and 3
Explanation: The Global Climate Change Alliance is an initiative of the European Union (statement 1 correct) that provides technical and financial support to vulnerable developing countries to mainstream climate change into development (statement 2 correct). It is coordinated by the EU, not by WRI and WBCSD, so statement 3 is wrong. Hence 1 and 2 only.
- Q6.Pollution
With reference to the 'Fly Ash' produced by thermal power plants, consider the following statements: 1. It can be used in the production of bricks. 2. It can be used as a replacement for some of the cement in concrete. 3. It contains some toxic heavy metals. Which of the statements given above is/are correct?
- a)1 and 2
- b)2 only
- c)1 and 3
- d)1, 2 and 3
Explanation: Fly ash is used to manufacture bricks (statement 1), can replace a portion of cement in concrete (statement 2), and contains toxic heavy metals such as arsenic, lead and mercury (statement 3). All three statements are correct.
- Q7.Climate Change
Consider the following statements: 1. Climate and Clean Air Coalition (CCAC) to Reduce Short Lived Climate Pollutants is a unique initiative of G20 group of countries. 2. The CCAC focuses on methane, black carbon and hydrofluorocarbons. Which of the statements given above is/are correct?
- a)1 only
- b)2 only
- c)Both 1 and 2
- d)Neither 1 nor 2
Explanation: The CCAC is a voluntary partnership of governments, intergovernmental organisations and others, not a G20 initiative, so statement 1 is wrong. It focuses on short-lived climate pollutants such as methane, black carbon and hydrofluorocarbons, so statement 2 is correct. Only statement 2 is correct.
- Q8.Agriculture
Which of the following practices can help in water conservation in agriculture? 1. Reduced or zero tillage of the land 2. Applying gypsum before irrigating the field 3. Allowing crop residue to remain in the field. Select the correct answer using the code given below:
- a)1 and 2 only
- b)3 only
- c)1 and 3 only
- d)1, 2 and 3
Explanation: Reduced or zero tillage conserves soil moisture (1), applying gypsum improves soil structure and water infiltration in some soils (2), and leaving crop residue reduces evaporation and conserves moisture (3). All three help conserve water in agriculture.
- Q9.Conservation
With reference to the 'Eco-Sensitive Zones (ESZs)' notified around protected areas, consider the following statements: 1. The boundaries of ESZs are fixed uniformly at 10 km around the protected areas. 2. Commercial mining is prohibited within ESZs. Which of the statements given above is/are correct?
- a)1 only
- b)2 only
- c)Both 1 and 2
- d)Neither 1 nor 2
Explanation: The extent of Eco-Sensitive Zones is not fixed uniformly at 10 km; it varies from area to area depending on the situation, so statement 1 is wrong. Commercial mining is among the prohibited activities within ESZs, so statement 2 is correct. Only statement 2 is correct.
- Q10.Wildlife Conservation
The term 'M-STrIPES' is sometimes seen in the news in the context of:
- a)Captive breeding of Wild Fauna
- b)Maintenance of Tiger Reserves
- c)Indigenous Satellite Navigation System
- d)Security of National Highways
Explanation: M-STrIPES (Monitoring System for Tigers - Intensive Protection and Ecological Status) is a software-based monitoring system used for the maintenance and management of tiger reserves. Hence option (b).
- Q11.Wildlife Conservation
Recently there was a proposal to translocate some of the lions from their natural habitat in Gujarat to which one of the following sites?
- a)Corbett National Park
- b)Kuno Palpur Wildlife Sanctuary
- c)Mudumalai Wildlife Sanctuary
- d)Sariska National Park
Explanation: The proposal was to translocate some Asiatic lions from the Gir forest in Gujarat to the Kuno Palpur Wildlife Sanctuary in Madhya Pradesh, to establish a second population. Hence option (b).
