Estuaries are unique environments to which plants and animals have specially adapted. Tidal influences and the abundance of life also create a wealth of food sources for animals. Either way, animal decomposers keep down the dead matter of plant and animal waste to make room for new growth and regrowth in the ecosystem. Saltwater is heavier than freshwater, so estuarine currents sink and move near the bottom of the estuary.When less-dense freshwater from a river flows into the estuary, it has an anti-estuarine current.
