Living Things

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

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

Reproduction – producing offspring (new individuals)

Response – a reaction to a stimulus Stimulus – a change in the environment that

causes a response

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)
