How do trees contribute to air quality improvement?

• A. They produce carbon dioxide during photosynthesis
• B. They filter pollutants and provide oxygen through photosynthesis
• C. They absorb all pollutants without exception
• D. They generate heat in the environment

Answer: (B)

Trees play a crucial role in enhancing air quality primarily through their ability to filter pollutants and provide oxygen during the process of photosynthesis. Photosynthesis involves trees taking in carbon dioxide from the atmosphere and, using sunlight, converting it into oxygen and glucose. This not only helps to reduce the concentration of carbon dioxide— a significant greenhouse gas— in the air but also increases the oxygen levels vital for the survival of most living organisms. Additionally, trees can filter out various airborne pollutants, such as dust, smoke, and other particulate matter. The leaves and bark of trees can trap these particles and prevent them from remaining airborne, which contributes to healthier air quality. Through their combined processes of photosynthesis and pollutant filtration, trees significantly improve the atmosphere, making it cleaner and more breathable for both humans and wildlife.
