Test: Forest: Our Lifeline - Class 7 MCQ

Forests are characterized by the presence of a dense vegetation cover, abundance of wildlife, and rich biodiversity. They are defined by the presence of a significant number of trees.

Forests are primarily used for timber production, providing wood for construction, furniture, and other purposes. They also serve as recreational spaces for activities like camping, hiking, and wildlife viewing.

In a forest ecosystem, plants and animals are interdependent. Plants provide shelter, food, and breeding grounds for animals, while animals aid in seed dispersal, pollination, and nutrient recycling.

Trees play a vital role in forests. Through photosynthesis, they produce oxygen, absorb carbon dioxide, and regulate the climate. Their roots hold the soil together, preventing erosion and maintaining stability.

If forests disappear, there would be severe consequences. Loss of biodiversity, climate change, global warming, soil erosion, and the disruption of various ecosystems are among the potential outcomes.

Forest conservation is crucial for sustaining biodiversity, maintaining ecological balance, and preserving natural resources like timber, medicinal plants, and water sources.

India is home to tropical rainforests, temperate forests, and mangrove forests. Desert forests do not exist in India due to the arid climate of its desert regions.

The profile of a forest refers to the distribution and arrangement of trees and other vegetation within a particular forest area. It helps in understanding the forest ecosystem.

Conservation of water resources is an indirect benefit of forests, as they help regulate the water cycle

Timber is a direct product of forests, while honey, medicinal plants, and tendu leaves are non-timber forest products.

Bengal tigers are commonly found in the tropical rainforests of India, which are home to a variety of wildlife.

Deforestation in India is primarily caused by agricultural expansion, urbanization, industrialization, mining, and construction activities.

The Forest Conservation Act, 1980, regulates the diversion of forest land for non-forestry purposes, mandates afforestation and reforestation programs, and provides for the conservation of forests and wildlife.

Anthropogenic factors are those caused by human activities. Deforestation is a major anthropogenic factor affecting forests.

The main objective of forest management is to maintain ecological balance by ensuring sustainable use of forest resources while preserving biodiversity and protecting wildlife habitats.

Community participation is crucial for successful forest conservation. It helps raise awareness, involve local communities in decision-making, and promote sustainable forest use practices.

Afforestation refers to the process of planting trees in areas where there was no forest cover previously. It helps in soil conservation, carbon sequestration, and biodiversity conservation. It is not intended for agricultural expansion.

The Chipko movement was a forest conservation movement that originated in India in the 1970s. It was a movement against deforestation and commercial logging.

Keystone species are those whose presence or absence has a significant impact on the ecosystem. In a forest ecosystem, wolves are an example of a keystone species because they help regulate the population of other animals, such as deer, which can have a negative impact on the ecosystem if their population grows unchecked.

Afforestation, forest conservation, and reforestation are all strategies for reducing the impact of climate change on forests. These measures help increase carbon sequestration, promote biodiversity conservation, and protect wildlife habitats.
