Revise: Effects of Climate ChangePopulations may therefore decline and species may become extinct, reducing biodiversity. These changes can spread through food webs: if one species declines, its predators, prey or pollinated plants may also be affected. Marine and coastal ecosystems can be harmed by warming water, rising sea levels and changing ocean chemistry.
For “describe briefly four potential effects”, give four distinct effects rather than four versions of flooding. Suitable choices include sea-level rise, altered rainfall and extreme weather, pressure on food or water supplies, and habitat or biodiversity loss.
