1. Living Things

2. Vocabulary
Autotroph (Producer) – Organism that makes it’s own food by using the Sun’s energy through photosynthesis
Cells – basic building blocks of living things
Competition – when organisms fight over limited (not enough) resources (food, water and oxygen)
Heterotroph (Consumer) – can not make their own food, they must eat for energy
Homeostasis (Regulation) – maintaining a stable internal environment and temperature

3. Vocabulary
Metabolism – all the chemical reactions (building and breaking down) that occur in an organism
Photosynthesis – the process of making food (glucose) by using the Sun’s energy, water and carbon dioxide

19. 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)
