The significance of studying the effects of climate change on marine food webs lies in understanding how changing conditions disrupt interactions between species, impacting nutrient cycling and energy flow. Alterations in temperature, ocean acidification, and changing salinity affect the productivity of primary producers like phytoplankton, subsequently influencing the entire food web. Disruptions can lead to cascading effects, endangering key species and altering community dynamics. Research in this area is crucial for developing adaptive management strategies to preserve marine biodiversity and ecosystem services, ultimately ensuring the stability and resilience of marine environments amid ongoing climate challenges.
