Why is conservation of biodiversity necessary?

Answer and explanation

Correct answer: It helps maintain life-support systems and ecological balance on Earth

The correct answer is A. Biodiversity includes the variety of genes, species and ecosystems. This variety supports food webs, pollination, nutrient cycling, soil formation, water regulation and ecosystem stability. It also provides useful resources such as foods, fibres and medicines and gives species the genetic variation needed to adapt to change. Option B is wrong because conservation benefits natural ecosystems and human societies, not only zoos. Option C is not the purpose of conservation; uncontrolled timber extraction can reduce biodiversity. Option D is false because the loss of species and habitats can damage ecological services and human well-being. Memory cue: biodiversity supports balance, resources and resilience.
