Worked practice questions

Which of the following is a DECOMPOSER in a typical ecosystem?

  1. Tiger in a forest food chain ecosystem
  2. Mango tree in a garden ecosystem
  3. Bacteria breaking dead leaves in soil
  4. Wheat plant in a Punjab field farm
Show answer and solution

Correct answer: C. Bacteria breaking dead leaves in soil

Decomposers break down dead organic matter into simple compounds, recycling nutrients to soil. Bacteria and fungi are the main decomposers.

The ozone layer protects life on Earth by:

  1. Reflecting visible sunlight back into space at noon
  2. Holding Earth's heat through the greenhouse effect
  3. Generating breathable oxygen continuously each day
  4. Blocking harmful UV-B and UV-C radiation from the Sun
Show answer and solution

Correct answer: D. Blocking harmful UV-B and UV-C radiation from the Sun

Ozone in the stratosphere blocks harmful UV-B and UV-C radiation. Without it, skin cancer, cataracts, and ecological damage would surge.

Which of the following is BIODEGRADABLE waste?

  1. Plastic bags and disposable bottles
  2. Glass containers and aluminium cans
  3. Vegetable peels and dry tree leaves
  4. Mercury-bearing batteries and CFL lamps
Show answer and solution

Correct answer: C. Vegetable peels and dry tree leaves

Biodegradable waste is broken down by microorganisms: vegetable peels, tree leaves, paper, cloth, kitchen waste. Plastic, glass, metals and batteries are non-biodegradable.
