Question

In an ecosystem there was loss of biodiversity due to some project in that area.

List two major causes of loss of biodiversity.

Answer 1

1. Habitat destruction and fragmentation: conversion of natural habitat (clearing, development, fires, overgrazing, soil changes) removes the places species need to live, breed, and feed, and fragments populations, causing them to decline or go locally extinct.
2. Invasion by alien (non‑native) species: Aggressive introduced species can outcompete, prey on, or chemically inhibit native species, leading to declines or elimination of local species.
