Imagine you are a water molecule, carbon atom, or nitrogen atom that is inside a cow. Write a brief explanation of how you got from the atmosphere (the air) into the biosphere (the living cow). *

Explanation:

The processes involved in each of the molecules involved are different.

For example, water molecules that have condensed in the atmosphere (in the cloud) return back to the earth through precipitation in the form of rain water. These cows drink these water from various water bodies around them. This is one process in which water molecules move from the atmosphere into the living cow.

In the case of carbon and nitrogen atoms; the air the cow breath in consists of nitrogen, oxygen, carbon dioxide and some other gases. These gas molecules move (from the atmosphere) into the cow through the process of respiration.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
