Question

(a) Taking one example each of habitat loss and fragmentation, explain how are the two responsible for biodiversity loss.
(b) Explain two different ways of biodiversity conservation.

Answer 1

Answer:

a. Habitat loss and fragmentation are responsible for biodiversity loss.

i. Habitat loss: The most dramatic examples of habitat loss come from tropical rain forestsThe Amazon rainforest (called the “lungs of the planet”) is being cut and cleared for cultivation of soya beans and for conversion into grasslands for raising beef.

ii. Fragmentation: When large-sized habitats are broken or fragmented due to human settlements, building of roads, digging of canals, etc., the population of animals requiring large territories and some animals with migratory habitats declines.

b. The two different ways of biodiversity conservation are:

i. Ex situ: In this conservation threatened organism are taken out from the natural habitat and placed in special setting with care and protected. Example- zoological park, botanical garden.

ii. In situ conservation: In this conservation threatened organisms are conserved in their natural habitat. Example-national parks, biosphere reserves.
