How does pollution affect the biodiversity in an ecosystem?

Pollution can have detrimental effects on the biodiversity of an ecosystem. In South Africa, industrial pollution and agricultural runoff can contaminate water sources, leading to a decline in aquatic species. Air pollution from factories and vehicles can harm plant life and disrupt food chains, impacting the entire ecosystem. Additionally, chemical pollutants can accumulate in the soil, affecting the health of microorganisms and plants. These disruptions can result in reduced species diversity and even extinction. It's crucial for Grade 11 students studying Science, Biology, and Ecology in South Africa to understand the far-reaching consequences of pollution on biodiversity.
