Question

what factor is the primary cause of earths decreasing biodiversity?
multiple choice
overexploitation
habitat loss
introduced species
artificial selection

Explanation:

Habitat loss is a major driver of biodiversity decline. When natural habitats are destroyed (e.g., through deforestation, urbanization, or conversion to agricultural land), species lose their homes, food sources, and breeding grounds. Overexploitation (like over - hunting or over - fishing) can also harm species, but habitat loss affects a wider range of species across different ecosystems. Introduced species can disrupt native ecosystems, but again, habitat loss has a more pervasive impact. Artificial selection is mainly related to human - controlled breeding in domesticated plants and animals and is not a primary cause of global biodiversity loss.
