Question

the hydrologic cycle... does not include glaciers. relies on evaporation and precipitation to help move water through ecosystems. purifies water for use by organisms. does not need the sun to operate.

Explanation:

The hydrologic cycle involves evaporation of water (powered by the Sun) from water - bodies, plants etc., and precipitation which redistributes water in ecosystems. Glaciers are part of it as they store and release water. It does not directly purify water for organisms in the main cycle process and it needs the Sun for evaporation.

Answer:

B. Relies on evaporation and precipitation to help move water through ecosystems
