Answer Key with Explanations
1. C – A resource in ecology is any factor organisms use to survive, grow, or reproduce.
2. C – Soil nutrients are non-living (abiotic) and essential for plant life.
3. D – Plants are living components and thus biotic resources.
4. D – Non-renewable resources cannot be replenished on a human timescale.
5. C – Wind is renewable because it is constantly generated naturally.
6. C – Sunlight is the main energy source driving photosynthesis.
7. D – Plastic is synthetic, not a natural resource.
8. C – Carrying capacity refers to the limit of resources an environment can supply.
9. C – Competitive exclusion happens when two species compete for the same limited resource.
10. C – Overexploitation leads to the depletion or exhaustion of resources.
11. C – Crop rotation preserves soil fertility and promotes sustainable use.
12. B – Forests produce oxygen, a vital ecological service and resource.
13. C – Water is essential for biological processes and as a habitat for many species.
14. B – A limiting resource is the one that constrains growth due to its scarcity.
15. B – Species may migrate or die off if they lack essential resources.
16. C – Fossil fuels take millions of years to form, making them non-renewable.
17. A – For a resource to be renewable, it must replenish at the same rate or faster than it is used.
18. C – Pollution and deforestation are major human impacts on resources.
19. C – Air is shared globally; pollution in one country can affect others.
20. C – Conservation ensures resources are used wisely and preserved for future generations.
