Question
- A. The ecosystem will remain unchanged
- B. The ecosystem may collapse or change significantly
- C. Only the removed component will be affected
- D. All components will adapt immediately
Answer
The correct answer is The ecosystem may collapse or change significantly.
Explanation
The correct option is The ecosystem may collapse or change significantly. The ecosystem may collapse or change significantly is correct because it directly matches the approved learning objective to explain the balance between ecosystem components. This belongs to Ecosystems within Section B: The living world, so the answer must stay focused on the geographical process, evidence, place, or impact named by the curriculum. The other options are weaker because they move away from Ecosystems, reverse the geographical relationship, or make a broader claim than the objective supports.
Common mistake
Misunderstanding Ecosystem Balance
Students often think that all components of an ecosystem are equally important and can be changed without affecting the others.
Emphasize that each component has a specific role and that changes to one can significantly impact the entire ecosystem.
