Cycles in Ecosystems

Cycles in Ecosystems. The Water Cycle. Water never leaves the Earth. It is constantly being cycled through the atmosphere, ocean, and land . This process, known as the water cycle , is driven by energy from the sun. The water cycle is crucial to the existence of life on our planet.
