Match the term with its description.

• Photosynthesis

• The only nutrient cycle that does not have an atmospheric component

• Sedimentation

• In this process, sunlight is used to convert carbon dioxide into sugars

• Transpiration

• This is the evaporation of water from plants

• Lightning

• This weather phenomenon can break apart/split nitrogen molecules

• Phosphorus cycle

• Phosphate ions can be released from sedimentary rocks
