Deep Water Currents -- Thermohaline Circulation. The gazelles are a food source for cheetahs. The saltiness of water is one factor that affects its density. Two species each occupy a smaller niche when they live together than they would if they lived alone. Because of their size, small isolated islands accumulate more species by chance. This phenomenon is explained by Adding heat decreases the density of water, while adding salt increases the density of water. on this page to learn more about these process and phenomena.

Being both cold AND salty makes it really dense, so it can sink very far. Others are confined to particular regions and form slow-moving, circular pools. Why are decomposers important to ecosystems? 3.13 shows the surface winds that flow from regions of high atmospheric pressure over the world's oceans. As the world warms due to increased levels of greenhouse gases in the atmosphere from human activities, changes in ocean and atmospheric circulation patterns will alter regional climate and ecosystems around the globe.
