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
Characteristics of Living Things
1. Cells
Unicellular
_______________________
- organisms that are made
up of only one cell ex. Bacteria and Protists
Multicellular
_______________________
- organisms that are made
up of more than one cell ex. Plants and Animals

Needs of Living Things
4. Living Space
Enough area is needed for organisms to obtain
resources (food, water, and oxygen)
_______________

fight over limited
not enough resources causing those with the
(________________)
survive
best traits to _____________
Needs of Living Things
Regulation
5. Homeostasis (______________)
Maintaining a proper body temperature
Warmblooded – body temperature
stays the same despite the environment
___________________
changes
Coldblooded – body temperature ____________

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)
