Biodiversity
What is biodiversity?
The variety of life in a particular habitat or ecosystem.
Name one of the five major ecosystems studied in class.
Answer: Amazon Rainforest, Coral Reefs, Sahara Desert, African Safari, Galapagos Islands.
What are three factors that can influence survival in different biomes?
Answer: Temperature, light, and soil quality.
What is adaptation in the context of living organisms?
Answer: The process by which organisms change over time to better survive in their environments.
What is one major threat to biodiversity?
Answer: Habitat loss due to deforestation.
Name one reason why biodiversity is important
It helps ecosystems function effectively and supports human survival.
What is the difference between a biome and an ecosystem?
Answer: A biome is a larger area defined by climate and geography, while an ecosystem is a community of living organisms and their environment.
Define global warming.
Answer: The gradual increase in Earth's average surface temperature due to human activity and greenhouse gas emissions.
Give an example of a structural adaptation in animals.
Any relevant e.g.The long neck of a giraffe, which helps it reach high leaves.
Name one conservation effort that could help protect endangered species.
Answer: Establishing protected areas or wildlife reserves.
What are two examples of endangered species?
Examples could include the Amur leopard and the Sumatran orangutan
Which ecosystem is known for its extreme temperatures and lack of rainfall?
Answer: The Sahara Desert.
Name one effect of climate change on polar ecosystems.
Answer: Melting ice caps and loss of habitat for polar animals.
How do polar bears adapt to their environment?
Any relevant e.g. They have thick fur and a layer of fat for insulation against the cold.
How do invasive species threaten native ecosystems?
Answer: They compete for resources, often leading to declines in native species.
What does it mean for a species to be extinct?
It means the species no longer exists anywhere on Earth.
What adaptations might you find in organisms living in coral reefs?
Answer: Bright colors for camouflage and specialized feeding mechanisms.
What is the greenhouse effect?
Answer: The trapping of heat in the Earth's atmosphere by greenhouse gases.
What is natural selection?
Answer: The process by which organisms better adapted to their environment tend to survive and produce more offspring.
What role do humans play in conservation efforts?
Answer: Humans can implement policies, educate others, and participate in restoration projects.
Describe one human activity that threatens biodiversity.
Habitat destruction due to urbanisation or deforestation.
What is the unique animal living on the Galapagos Islands?
Answer: Galapagos Giant Tortoise
Describe one human activity that contributes to climate change.
Answer: Burning fossil fuels for energy.
Why is it important for organisms to adapt to their environments?
Answer: Adaptations increase their chances of survival and reproduction.
Describe the importance of preserving biodiversity for future generations.
Answer: It ensures ecosystem resilience and the availability of resources for future human use.
