Living Things

Vocabulary Autotroph (Producer) – Organism that makes its 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

Vocabulary Homeostasis (Regulation) – maintaining a stable internal environment and temperature Metabolism – all the chemical reactions (building and breaking down) that occur in an organism Locomotion- the movement of an organism

Vocabulary 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. Made of Cells _______________ - organisms that are made up of only one cell ex. Bacteria and Protists _________________ - organisms that are made up of more than one cell Usually can be seen with the naked eye. ex. Plants and Animals Unicellular Multicellular

Check what you know Heterotroph Autotroph

Needs of Living Things It helps organisms to: 2. Water Reproduce Break down food Grow ________________ substances within their bodies Reproduce Transport

Needs of Living Things 3. Living Space It provides organisms with: A _________ where they can get _____________ (food, water, oxygen). Organisms often ____________ for space. _________________: when organisms _______ over limited (________________) resources causing those with the best traits to ___________ place resources compete Competition fight

Needs of Living Things 4. Maintain Homeostasis (Regulation) • It allows organisms to: maintain ________ conditions internally (inside the body) Control temperature Control the amount of water maintain cell functions stable

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)
