Sample questions

1. Which of the following is NOT a component of the natural environment?

   1. Rivers and oceans
   2. Mountains and valleys
   3. Buildings and roads
   4. Plants and animals
   Show answer

   Answer: C. Buildings and roads

   The natural environment consists of living (biotic) and non-living (abiotic) components that occur naturally on Earth. Buildings and roads are man-made structures and are part of the artificial or built environment.

2. What does 'biodiversity' refer to?

   1. The variety of landforms on Earth
   2. The variety of weather patterns
   3. The variety of life in all its forms within a given ecosystem or on Earth
   4. The study of rocks and minerals
   Show answer

   Answer: C. The variety of life in all its forms within a given ecosystem or on Earth

   Biodiversity encompasses the vast range of different life forms, including plants, animals, fungi, and microorganisms, as well as the ecosystems they inhabit and the genetic variations within them.

3. Which of the following is a primary pollutant that directly harms human health and the environment?

   1. Ozone (O3) formed in the troposphere
   2. Sulfur dioxide (SO2) emitted from burning coal
   3. Nitric acid (HNO3) formed from NOx
   4. Sulfuric acid (H2SO4) formed from SO2
   Show answer

   Answer: B. Sulfur dioxide (SO2) emitted from burning coal

   Sulfur dioxide is a primary pollutant, meaning it is emitted directly from a source (like burning coal) and can cause respiratory problems and contribute to acid rain. Ozone, nitric acid, and sulfuric acid are often secondary pollutants, formed in the atmosphere through chemical reactions.

4. What is the purpose of conservation efforts?

   1. To exploit natural resources as quickly as possible
   2. To protect and manage natural resources for present and future generations
   3. To increase pollution levels
   4. To promote the extinction of species
   Show answer

   Answer: B. To protect and manage natural resources for present and future generations

   Conservation aims to safeguard natural resources, ecosystems, and biodiversity, ensuring their availability and health for both current needs and the long-term well-being of the planet.

5. What is a food web?

   1. A single path of energy flow in an ecosystem
   2. A complex network of interconnected food chains showing the feeding relationships between organisms
   3. The process of photosynthesis
   4. The life cycle of a particular animal
   Show answer

   Answer: B. A complex network of interconnected food chains showing the feeding relationships between organisms

   A food web illustrates how energy is transferred through an ecosystem by showing the multiple feeding relationships between different organisms, unlike a simple food chain.
