5 kingdoms:

animals plants fungi e.g mushrooms protist e.g seaweed monera e.g bacteria

__Keys__ - make classifications easier Good key is: We us them because: Dichotomous keys Process for sorting all living things called taxonomy EG. Humans- homo sapiens
 * Simple, easy to follow representations of classification systems
 * Clear
 * Simple
 * Easy to use
 * Easier than detailed descriptions
 * Show at a glance distinguishing characteristics
 * Make it easy to identify objects not seen before
 * Give consistent answers, regardless of who is using them
 * Must common branching keys
 * 2 choices at each branch
 * Start at the tip with a large group, progressively dividing into smaller groups.

classification key: kingdom phylum class order genus species

We use systems of classification to look for patterns and make inferences about situations. How and why do we group things?"

biologists use a set of characteristics to help decide if something is living or not.

characteristics common to ALL living things: Individual that has life is referred to as an organism some non-living thing possess characteristics but not all e.g. fire or water. __Animals__ they are heterotrophs. Means they cannot make their own food, and must eat to survive. Food is digested into glucose Glucose provides all the energy the animal needs. Process is called cellular respiration. Glucose + oxygen =>energy + carbon dioxide + water. c₆ H₁₂ o₆ + ₂ => CO₂ + H₂O endotherms or endothermic (warm blooded) Ectothermic or ectoderms (cold blooded) __Plants__ Plants produce glucose from the process of photosynthesis Carbon dioxide + water + energy=> glucose + oxygen
 * 1)  Movement
 * 2)  Reproduce
 * 3)  Growth
 * 4)  Take in and use gases from the air or water
 * 5)  Take in energy for use
 * 6)  Produce waste
 * 7)  Respond to stimuli
 * 8)  Made of cells

organisms that produce their own food are called autotroph
