Biodiversity and Conservation
Grade 7 · Science · Ecology · Idaho, USA
Lesson Summary
Understand why having many different species matters and what we can do to protect them.
Explanation
Biodiversity refers to the variety of life in an area, including the number of different species, the genetic diversity within species, and the variety of ecosystems. High biodiversity makes ecosystems more resilient because if one species is lost, others can fill its role. Threats to biodiversity include habitat destruction, pollution, climate change, and invasive species. Conservation efforts like protecting habitats, creating wildlife corridors, and breeding endangered species help maintain biodiversity.
Practice Questions
Q1: Why is biodiversity important for an ecosystem?
Answer: High biodiversity makes an ecosystem more stable and resilient. A wider variety of species means the ecosystem can better withstand and recover from changes or disturbances.
Q2: Name two human activities that threaten biodiversity.
Answer: Habitat destruction (like deforestation) and pollution are two major human threats to biodiversity (others include overhunting and introducing invasive species).
Q3: What is one way people can help conserve biodiversity?
Answer: Protecting natural habitats through national parks and wildlife reserves prevents species from losing the environments they need to survive.
