FAQs on Thorn Forests and Scrubs Video Lecture - Class 9

1. What is a thorn forest?

Ans. A thorn forest is a type of vegetation found in arid and semi-arid regions, characterized by the presence of trees and shrubs with thorny leaves. These forests are adapted to survive in dry conditions and typically have low rainfall.

2. What are the main features of a scrub forest?

Ans. Scrub forests, also known as shrublands, are characterized by the presence of low-growing vegetation, including shrubs, small trees, and grasses. These forests are found in areas with poor soil and low moisture content. They often have a dense and tangled growth pattern.

3. How do thorn forests and scrubs adapt to arid conditions?

Ans. Thorn forests and scrubs have several adaptations to survive in arid conditions. They typically have deep roots to access groundwater, thick and waxy leaves to reduce water loss through transpiration, and thorns or spines to deter herbivores and reduce water loss through leaf consumption. They may also have reduced leaf sizes to minimize water loss.

4. What are the ecological benefits of thorn forests and scrubs?

Ans. Thorn forests and scrubs play a vital role in the ecosystem. They help prevent soil erosion and desertification by stabilizing the soil with their extensive root systems. These forests also provide habitats for various wildlife species, including insects, birds, and small mammals. Additionally, they act as carbon sinks, absorbing and storing carbon dioxide from the atmosphere.

5. Are thorn forests and scrubs under threat?

Ans. Yes, thorn forests and scrubs are under threat due to various factors. Deforestation, overgrazing by livestock, and agricultural expansion are some of the significant threats to these ecosystems. Climate change and increased frequency of wildfires also pose a risk to their survival. Efforts are being made to conserve and restore these habitats to maintain their ecological importance.
