Climate change greatly affects the community of whales and dolphins. Most of the species of whales live in a specific temperature range, because of the non-availability of their food, zoo plankton in warm waters. One of the most important organisms whales prey up on are zoo plankton, whose number declined greatly due to the warming of oceans. These whales migrate to Northern waters overcome the effects of increasing temperature and in search of food. So ,we can expect a disruption in the food chain as a result of the warm oceanic waters.
