Cells – basic building blocks of living things
Competition – when organisms fight over limited (not enough) resources (food, water and oxygen)

24. 6th Grade Review Material: Energy Transformation
Energy moving from one object to another
Heat from the Sun is transferred/absorbed by a pool causing the water to evaporate
After swimming your bathing suit absorbs heat from the Sun causing the water to evaporate and your suit to dry
The Sun's heat is received by the Earth by radiation (heat transferred through empty space)
