You are a molecule of water. Choose a starting point in the water cycle and describe the process you would go through to move through the entire cycle.
I begin as a water molecule in a lake. As the sun heats the surface, I evaporate into the atmosphere. As I rise higher, I cool down and undergo condensation to form a cloud. When the droplet grows large enough, I fall back to Earth as precipitation. I eventually seep into the soil and return to a reservoir as groundwater. I remain there temporarily until I am evaporated again to repeat the cycle.
You are a molecule of carbon. Choose a starting point in the carbon cycle and describe the process you would go through to move through the entire cycle.
Carbon in carbon dioxide gas is taken in by plants for photosynthesis. Plants turn the carbon atom into a carbohydrate. An animal eats the plant and uses its carbohydrates for energy. During respiration, the animal releases carbon dioxide back into the atmosphere.

You are a molecule of nitrogen. Choose a starting point in the nitrogen cycle and describe the process you would go through to move through the entire cycle.
Bacteria perform nitrogen fixation. More bacteria perform nitrification. Nitrogen, in usable form, is taken up by plants and assimilated into their proteins (becoming part of the plant). An animal eats the plant and the nitrogen becomes part of the animal’s proteins. An animal dies and decomposes, or excretes waste, returning the nitrogen to the soil.

You are a molecule of phosphorus. Choose a starting point in the phosphorus cycle and describe the process you would go through to move through the entire cycle.
Phosphorus cycles between living things and the soil. Plants absorb phosphates from the soil and turn them into organic compounds through assimilation. Animals eat plants and pass the phosphorus through the food chain from one animal to the other. An animal dies and decomposes, returning the phosphorus to the soil.

Check the items you included.The water molecule in the lake evaporates.The water molecule cools and undergoes condensation.The water droplet increases in size, then falls to the Earth in the form of precipitation.The precipitation returns to a reservoir, in this case, ground water.The water remains in the reservoir temporarily before it is evaporated and begins the process again.
