Explanation written with AI and checked against the answer key

Analyze the question: The question uses "does not," so we are looking for the statement that is not a result of conservation. Three options will be benefits of conservation, and one will be false.

Explain the concept: Conservation is the careful management and protection of natural resources (forests, wildlife, water, soil) so they last for future generations. Its main aims are:

  • Maintaining ecological balance
  • Protecting species from extinction
  • Preserving natural beauty and habitats
  • Supporting tourism and the economy (e.g., Yankari Game Reserve and Cross River National Park in Nigeria)

Step-by-step solution:

  • A. Maintain a balanced ecosystem. Conservation does this, since protected species and habitats keep food chains and nutrient cycles stable. This is true of conservation, so it is not the answer.
  • B. Preserve the beauty of nature. Conservation does this, since protected landscapes, forests, and wildlife stay intact. This is true, so it is not the answer.
  • C. Attract tourists. Conservation does this, since reserves and parks draw visitors and earn revenue. This is true, so it is not the answer.
  • D. Threaten the survival of species. Conservation does the opposite. It protects species from extinction. Since conservation does not do this, D completes the sentence correctly.

Answer: D. Conservation protects species. It does not threaten their survival.

Tip: When a question says "does not," "except," or "which is NOT," first mark the options that are true, and the leftover false one is your answer. Here, the one negative-sounding option (threaten) clashes with the positive purpose of conservation.
