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 Characteristics of Living Things 2. Locomotion Move Can ___________ Characteristics of Living Things 3. Metabolism All chemical reactions that occur in an organism in food (eating) Ingestion – taking _____ breakdown food into useable Digestion - __________________ nutrients Characteristics of Living Things Respiration – nutrients (food) combine with oxygen to produce energy and carbon _______________ dioxide wastes (solid, Excretion – getting rid of ____________ liquid, or gas CO2) Characteristics of Living Things 4. Growth Increase in size and complexity divide for growth and Multicellular cells ___________ repair Characteristics of Living Things 5. Respond to the Environment change in the environment that Stimulus – a ___________ causes a response ex. Cold reaction to a stimulus ex. shiver Response – a ____________ Characteristics of Living Things 6. Reproduce individuals (offspring) Produce new _______________________________ species Needed for survival of a ______________ Characteristics of Living Things Asexual Reproduction one parent Requires __________ identical to Offspring are physically and genetically _______________ the parent Examples: Unicellular organisms dividing (Mitosis) Plant Clippings Regeneration Budding Cloning Characteristics of Living Things Sexual Reproduction two parents Requires __________ not physically and genetically Offspring are ______ identical to the parent characteristics They have a blending _____________ of traits (_____________________) variety among organisms Causes _______________ Examples: male and an egg Joining of a sperm (___________) (______________) female cell - fertilization male and an egg cell Joining of pollen (__________) Needs of Living Things 1. Energy Producers Autotrophs (_________________) Make their own food using the Sun’s energy by Photosynthesis _____________________ Plants Example: __________ Needs of Living Things Consumers Heterotrophs (_________________) Can’t make their own food __________ They must _________ eat for energy Animals Example: _______________ plants Herbivore – eats only ___________ animals Carnivore – eats only ______________ both plants and animals Omnivore eats ________ Needs of Living Things 2. Water Needed for chemical reactions to take place transport Dissolves substances for _______________ Needs of Living Things 3. Oxygen Needed for aerobic respiration (combining oxygen with food to produce energy __________ Most atmospheric oxygen comes from plants photosynthesis undergoing ____________________ Needs of Living Things 4. Living Space Enough area is needed for organisms to obtain resources (food, water, and oxygen) _______________ Competition – when organisms ________ 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 ____________ with the environment 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)
