Which statement best summarizes the water cycle?
as water moves through an ecosystem, its energy is lost between the trophic levels.
water in the atmosphere must be converted to another chemical before animals can use it.
the water on earth changes forms as it moves from one reservoir to another.

Option C

Explanation: The water cycle can be defined as the cyclic movement of water from one place to another in different forms is known as water cycle.

The water falls from the sky(precipitation) in the sea, ocean, lakes, glaciers and snow. When the temperature rise the water evaporates and goes into sky  and deposits in the clouds by the process of condensation.

This water falls again in the form of rain or snow back on to the earth, this cycle continues. The water changes from one form to another as it changes its places from clouds to earth and back from the earth to clouds.
