A warming climate and melting ice can have significant impacts on the Arctic cod and the entire food web. As sea waters warm and ice melts, it disrupts the delicate balance of the Arctic ecosystem. The changes in temperature and habitat can affect the availability of zooplankton, which is the primary food source for Arctic cod. This can lead to a decrease in their population and affect the organisms that rely on Arctic cod as a food source. It's a complex issue with far-reaching consequences for the Arctic ecosystem.
