FAQs on NCERT Textbook: Trees - English Honeycomb Class 7

1. What is the importance of trees?
Ans. Trees are important for several reasons. They help in reducing air pollution by absorbing carbon dioxide and releasing oxygen through the process of photosynthesis. Trees also provide shade, which helps to cool the environment and reduce energy consumption. Additionally, trees prevent soil erosion, provide habitat for animals, and contribute to the overall biodiversity of an area.
2. How do trees contribute to the water cycle?
Ans. Trees play a crucial role in the water cycle by influencing the movement of water. They absorb water from the ground through their roots and release it into the atmosphere through a process called transpiration. This moisture then condenses and forms clouds, ultimately leading to precipitation. The roots of trees also help in preventing water runoff and soil erosion, allowing water to be absorbed into the ground and replenish groundwater reserves.
3. How can trees help in mitigating climate change?
Ans. Trees help in mitigating climate change in several ways. Firstly, they absorb carbon dioxide, a greenhouse gas, from the atmosphere during photosynthesis and store it in their tissues. This helps to reduce the concentration of carbon dioxide in the atmosphere, thus mitigating the greenhouse effect. Additionally, trees provide shade, which helps to cool the surrounding environment and reduce the need for energy-consuming air conditioning. Lastly, forests act as carbon sinks, sequestering large amounts of carbon and preventing it from being released into the atmosphere.
4. What are some common threats to trees?
Ans. Trees face various threats, both natural and human-induced. Some common threats include deforestation, which involves the clearing of trees for agriculture, urbanization, or logging purposes. Pollution, including air and water pollution, can also negatively impact trees. Invasive species and pests can cause diseases that weaken or kill trees. Climate change, with its associated extreme weather events like droughts and storms, can also pose a threat to tree health and survival.
5. How can we contribute to tree conservation?
Ans. There are several ways in which individuals can contribute to tree conservation. Planting trees in urban areas or participating in tree-planting initiatives can help increase the tree cover and improve the environment. Supporting organizations and initiatives that work towards preserving forests and protecting trees is another way to contribute. Adopting sustainable practices, such as reducing paper consumption and recycling, can also help in conserving trees. Additionally, spreading awareness about the importance of trees and their conservation is crucial in inspiring others to take action.
