Why is biodiversity in an ecosystem so important?
Because it can help humans where to determine good places to develop farm land.
Because places that have a healthy biodiversity are unaffected by major disturbances.
Because having a high biodiversity allows ecosystems to withstand major changes.
Because having a high biodiversity allows for fewer opportunities of competition for similar resources.
