Q1: What is biodiversity?

Biodiversity is the variety of all living organisms (plants, animals, microorganisms) and their ecosystems on Earth. It includes genetic diversity within species, species diversity, and ecosystem diversity. High biodiversity indicates healthy ecosystems.

Q2: Define endangered species and extinct species with examples.

Endangered species: organisms facing high extinction risk in near future. Example: Indian rhino, Bengal tiger. Extinct species: organisms that no longer exist anywhere. Example: dodo bird, Steller's sea cow. Extinction is irreversible.

Q3: What is habitat destruction? How does it affect biodiversity?

Habitat destruction is the removal/degradation of natural environments through deforestation, urbanization, agriculture, pollution. It directly reduces available space for organisms, fragmenting populations, reducing genetic diversity, leading to species extinction and ecosystem collapse.

Q4: What are conservation strategies? Name three methods of wildlife conservation.

Conservation strategies protect species and ecosystems. Three methods: 1) National Parks and Wildlife Sanctuaries (protect habitats), 2) Protected habitats through legislation and regulations, 3) Captive breeding of endangered species, 4) Education and awareness programs.

Q5: What is a biosphere reserve?

A biosphere reserve is a region designated by UNESCO to conserve biodiversity and promote sustainable development. It has three zones: core zone (strict protection), buffer zone (limited human activity), transition zone (sustainable use). Example: Nilgiri Biosphere Reserve.

Q6: What are the causes of animal extinction?

Causes: 1) Habitat loss (deforestation, dam construction), 2) Poaching and overhunting, 3) Pollution (water, air, soil), 4) Climate change, 5) Competition from invasive species, 6) Disease outbreaks, 7) Fragmentation of populations.
