Question

1. which of the following is a direct consequence of climate change on marine ecosystems? a) loss of marine habitats b) increased fish biomass c) enhanced coral health d) decreased sea levels 10. how can individuals contribute to the preservation of marine ecosystems? a) by consuming more single - use plastics b) by supporting sustainable seafood choices c) by engaging in more fishing activities d) by advocating for coastal development

Explanation:

• For question 9: Climate change leads to rising temperatures and ocean acidification. Rising temperatures cause coral bleaching (not enhanced coral health), disrupt marine habitats. Ocean - related ice melting leads to rising sea levels (not decreased). And climate change generally disrupts marine food webs, so increased fish biomass is unlikely. Loss of marine habitats is a direct consequence.
• For question 10: Consuming more single - use plastics increases marine pollution. Engaging in more fishing activities can over - exploit fish stocks. Advocating for coastal development can destroy marine habitats. Supporting sustainable seafood choices helps maintain healthy fish populations and marine ecosystems.

Answer:

1. a) Loss of marine habitats
2. b) By supporting sustainable seafood choices
