PAG 3.1 the Calculation of Species Diversity Questions and Answers | Latest Version | Graded A+ **Why does an oak woodland climax community have high species diversity?** An oak woodland supports many species because it offers a wide variety of food sources and habitats. This biodiversity ensures that the loss of one species has minimal impact on the overall ecosystem. **Explanation:** Oak woodlands provide a complex and stable environment where different species can coexist. The variety of plants and animals in such an ecosystem creates a robust food web and numerous ecological niches, allowing many species to thrive. **How do farming practices lead to reduced species diversity?** Farming often involves monoculture, which reduces the variety of habitats available. The use of pesticides decreases the availability of food sources, and the removal of hedgerows eliminates habitats for many species. **Explanation:** Monoculture farming replaces diverse ecosystems with single-crop fields, drastically reducing the types of habitats. Pesticides kill not only pests but also beneficial insects and other animals, further decreasing biodiversity. Hedgerows, which provide shelter and food for various species, are often removed to create larger fields, exacerbating habitat loss. **What impact would planting hedges around fields have on species diversity?** Planting hedges would increase species diversity by providing more habitats and supporting a more complex food web. **Explanation:** Hedges create additional habitats and corridors for wildlife, helping to restore some of the natural diversity lost to monoculture farming. They offer food and shelter for a wide range of species, promoting a more balanced and resilient ecosystem.
