NEET BIOLOGY

Detailed explanation-1: -Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples.

Detailed explanation-2: -Habitat loss can fragment ecosystems and can cause species extinctions, while habitat restoration can increase local biodiversity and species populations. The evolution of life cycles and traits that help species survive and reproduce in distrubed or altered ecosystems.

Detailed explanation-3: -There are many causes of habitat loss, including land conversion for development from growing populations, mining for materials, harvesting lumber for paper products and, of course, agriculture.

Detailed explanation-4: -Destruction and degradation of natural ecosystems are the primary causes of declines in global biodiversity (1, 2). Habitat destruction typically leads to fragmentation, the division of habitat into smaller and more isolated fragments separated by a matrix of human-transformed land cover.

Detailed explanation-5: -The main modern causes of extinction are the loss and degradation of habitat (mainly deforestation), over exploitation (hunting, overfishing), invasive species, climate change, and nitrogen pollution.
