Ventilation systems are needed in a <span>multicellular organism to actually obtain oxygen and give out carbon dioxide. Without this ventilation system, it would be very difficult for multicellular organisms to survive. It has been also observed that surface diffusion is not enough for a multicellular organism to breath.</span>
Answer:
There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection
Explanation:
Evaporation- Is the the process in which water changes from a liquid to a gas or vapor.
Condensation- Is the process in which water vapor or gas in the air is changed into a liquid. Is the opposite of evaporation.
Precipitation- Precipitation is water from clouds in the form of rain, freezing rain, sleet, snow, or hail.
Collection- This is when water that falls from the clouds as rain, snow, hail or sleet, collects in the oceans, rivers, lakes, streams. Also some will soak into the ground and will collect as ground water.
