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.

How does the loss of pollinators, such as bees and butterflies, affect human resources and food production?

• Decreases food production because these pollinators are not important for agriculture

• Reduces food production as these pollinators are essential for many crops

• Has no effect on food production

How does biodiversity in an aquatic ecosystem contribute to the quality of clean water for human use?

• Biodiversity in aquatic ecosystems has no influence on water quality.
