Marine heatwaves serve as critical stressors on marine ecosystems, often resulting in mass mortality of species such as kelps and corals. This disruption leads to habitat degradation and affects the entire food web, showcasing the fragility of marine ecosystems in the face of climate change. As temperatures rise, many species struggle to adapt, posing serious challenges for biodiversity conservation.

Impact of Marine Heatwaves on Marine Ecosystems
Marine heatwaves are defined as prolonged periods of unusually high sea surface temperatures. Their effects on marine ecosystems are profound and multifaceted, primarily negative.
Mass Mortality of Species
- Marine heatwaves can lead to severe thermal stress for various marine organisms, particularly those that are sensitive to temperature changes.
- Species such as corals, shellfish, and certain fish are especially vulnerable, often experiencing mass die-offs when exposed to elevated temperatures.
- The mortality rates can be significant, resulting in large-scale declines of populations.
Disruption of Food Webs
- The loss of key species can disrupt the entire food web, as predators and prey relationships are altered.
- For example, when foundational species like phytoplankton or benthic organisms decline, this can lead to a cascading effect, impacting higher trophic levels, including commercially important fish species.
Long-Term Ecological Changes
- The aftermath of marine heatwaves can lead to shifts in community structure, with some species thriving while others decline or disappear.
- Invasive species may proliferate in the altered conditions, further complicating ecosystem dynamics.
Conclusion
In summary, option 'C' is correct because marine heatwaves cause mass mortality of various species, which disrupts the food web and has lasting impacts on marine biodiversity and ecosystem stability. Understanding these impacts is crucial for conservation efforts and managing marine resources effectively.
