Question

which best describes a role of animals in the water cycle?
they help water vapor condense when they produce waste.
they help water vapor condense when they inhale.
they release water vapor through transpiration.
they release water vapor when they exhale.

Explanation:

Animals release water vapor when they exhale (as part of respiration). Transpiration is a plant - related process (not animals). Inhaling does not condense water vapor. Producing waste is not directly related to the water cycle role of releasing water vapor.

Answer:

They release water vapor when they exhale.
