NGSS.MS-LS2-1

It is held within the spaces between the particles and organic content of the soil. It has high concentrations of carbon dioxide and water vapor, but little oxygen.

• air

• pores

• mineral particles

• organic matter

It is held within the soil pores and it is available for plant growth and can be drained or retained depending on the type of soil.

• air

• water

• mineral particles

• organic matter
