Multiple choice

How do the changes in the quantum of carbon dioxide in the atmosphere occur?

Directions: Read the passage and answer the question that follow:

Forests provide a wide range of goods and services. Goods include timber, fuel wood, as well as food products (berries, mushrooms, etc.) and fodder. As regards important services, forests and trees play a role in the conservation of ecosystems, in maintaining quality of water, and in preventing or reducing the severity of floods, avalanches, erosion, and drought. Forests provide a wide range of economic and social benefits, such as employment, forest products, and protection of sites of cultural value. Forests, like other ecosystems, are affected by climate change. The impact due to climate change may be negative in some areas, and positive in others. However, forests also influence climate and the climate change process mainly by effecting the changes in the quantum of carbon dioxide in the atmosphere. They absorb CO2 from atmosphere, and store carbon in wood, leaves, litter, roots and soil by acting as “carbon sinks”.

  1. Through conservation of ecosystems

  2. Through the economic and social benefits of forests

  3. Through the forests acting as carbon sinks
