Study Notes
Environmental change involves various factors that impact ecosystems, including habitat destruction, pollution, invasive species, and climate change. Preventing extinction focuses on conservation efforts like captive breeding and habitat protection to save endangered species.
Exam Tips
Key Definitions to Remember
- Habitat destruction — The process by which a natural habitat becomes incapable of supporting its native species.
- Pollution — The introduction of harmful materials into the environment.
- Invasive species — Non-native species that cause harm to the environment, economy, or human health.
- Endangered species — A species at risk of extinction.
- Captive breeding — Breeding of rare or endangered species in controlled environments.
Common Confusions
- Confusing habitat destruction with pollution as the same issue.
- Thinking all invasive species are harmful in every context.
Typical Exam Questions
- What is habitat destruction? Habitat destruction is when a natural habitat becomes incapable of supporting its native species.
- How does pollution affect the environment? Pollution introduces harmful materials that damage air, water, and land quality.
- What are invasive species? Invasive species are non-native species that can harm ecosystems.
What Examiners Usually Test
- Understanding of how different environmental changes impact biodiversity.
- Knowledge of conservation methods to prevent extinction.
- Ability to explain the effects of pollution and invasive species on ecosystems.
