# 3 Can Ocean Currents affect why organisms migrate and live in the specific geographical regions?

Currents affect living organisms by influencing food supply, water temperature and weather patterns. The three main causes of currents in the ocean are winds created by the earth's rotation and density differences in the ocean waters. So how are ocean currents playing a role in influencing where organisms live? The answer is a link that all organiss are interconnected together by in an ecosystem. The food chain! Currents are responsible for transporting nutrients and plankton from one area to another. An example is when fish heavily populate locations that have good food resources such as plankton, attracting larger predators such as tuna, birds and marine mammals and finally humans migrate to the nutrient rich environment. When warm water currents reach South America, plankton die because of the lack of nutrients in the warmed water current forces fish, such as anchoves to scatter to find food. This is an example of an ocean food chain that has been disrupted by ocean currents. Imagine this occurring daily in the most diverse part of the planet's oceans. In addition, ocean currents can slow down migration or speed it. It influences where plants and animals live and ultimately affects the settling of people in geographical, food rich, regions. When all is said and done, currents move our nutritional resources and heterotrophs must migrate to better resources. This is an simple explaination of how diverse life is on earth and how it's very success is driven by cycles occuring in the our ecosytem. We are all interconnected between living and non-living influences and currents make a gigantic influences on how and where organisms live successfully.
