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).

Solution: c)

Forest landscape restoration (FLR) is the ongoing process of regaining ecological functionality and enhancing human well-being across deforested or degraded forest landscapes. FLR is more than just planting trees – it is restoring a whole landscape to meet present and future needs and to offer multiple benefits and land uses over time.

FLR manifests through different processes such as: new tree plantings, managed natural regeneration, agroforestry, or improved land management to accommodate a mosaic of land uses, including agriculture, protected wildlife reserves, managed plantations, riverside plantings and more.

Solution: c)

The Bengal tiger is found primarily in India with smaller populations in Bangladesh, Nepal, Bhutan, China and Myanmar. It is the most numerous of all tiger subspecies with more than 2,500 left in the wild. The creation of India’s tiger reserves in the 1970s helped to stabilize numbers, but poaching to meet a growing demand from Asia in recent years has once again put the Bengal tiger at risk. The mangroves of the Sundarbans—shared between Bangladesh and India—are the only mangrove forests where tigers are found. The Sundarbans are increasingly threatened by sea level rise as a result of climate change.
