Dara studied the effects of urbanization on invertebrate diversity in a local stream. He counted the number of different invertebrate species at three sites with varying levels of urban development.
Explain how urbanization can alter environmental conditions in streams and affect invertebrate biodiversity.
Dara’s data showed:
Site A (rural): 18 species
Site B (suburban): 11 species
Site C (urban): 6 species
What trend is observed, and what inference can you make about the relationship between urbanization and biodiversity?
Which factor most directly contributes to reduced invertebrate diversity in urban streams?
Describe one ecological consequence of declining invertebrate diversity for stream ecosystems.
Which of the following mitigation strategies could help preserve stream biodiversity in urban areas?
Explain how invertebrate diversity can be used as a bioindicator of ecosystem health.
Claim:
Urbanization reduces biodiversity in aquatic ecosystems.
Use Dara’s data and reasoning to support this claim.
Propose one technological or policy-based strategy to reduce the impact of urbanization on stream ecosystems.
