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:

• Transpiration is a plant - related process (not animals), so the option about transpiration is incorrect.
• When animals exhale, they release water vapor as part of their respiratory process. Condensation during waste production or inhalation is not a typical role in the water cycle for animals in the way described in the first two options.

Answer:

They release water vapor when they exhale.
