2) Which nutrient is not cycled through the atmosph a) Carbon b) Nitrogen C)Phosphorus d) Water

## Step 1<br />The question is asking which nutrient among the given options does not undergo a cycle through the atmosphere. The options provided are Carbon, Nitrogen, Phosphorus, and Water.<br /><br />## Step 2<br />Carbon, Nitrogen, and Water are all nutrients that are cycled through the atmosphere. Carbon is cycled through the atmosphere via photosynthesis and respiration. Nitrogen is cycled through the atmosphere via nitrogen fixation, decomposition, and denitrification. Water is cycled through the atmosphere via the water cycle, which includes evaporation, condensation, and precipitation.<br /><br />## Step 3<br />However, Phosphorus does not cycle through the atmosphere. Phosphorus is a nutrient that is cycled through the soil and water, but not the atmosphere. This is because Phosphorus does not exist in a gaseous state under normal conditions on Earth.
