Understand the concept of biodiversity: Biodiversity refers to the variety and variability of life forms within a given ecosystem, biome, or the entire Earth. It includes the diversity of species, genetic variation, and ecosystems.
Identify the primary threats to biodiversity: Common threats include habitat destruction, climate change, pollution, overexploitation, and invasive species. These factors can lead to a reduction in biodiversity by causing species extinction or altering ecosystems.
Focus on habitat destruction: Habitat destruction is the process by which natural habitat is rendered unable to support the species present. This can occur through deforestation, urbanization, agriculture, and other human activities.
Explain why habitat destruction is a primary threat: When habitats are destroyed, the organisms that depend on them for survival are displaced or perish. This leads to a decrease in species diversity and can disrupt ecological balance.
Contrast with other options: Natural selection is a natural process that can lead to adaptation and evolution, not a direct threat. Symbiotic relationships often benefit biodiversity. Increased genetic diversity generally supports resilience and adaptability in ecosystems.
