__**What is a organism?**__

 * All organisms are a living thing that can respond to any type of stimuli. All organisms can reproduce and grow and develop though their lives.**

__Classification__
The process of organising organisms into groups based on predetermined criteria is called classification. The classification of living things is said to be __strong__, multilevel classification. strong, because the scheme gives predictable results. multilevel because major groupings may be further subdivided into smaller, subgroups. The criterion we use to assign organisms to groups is the closeness of the evolutionary relationships between members of the group. this is usually observed by looking at the number of features shared by organisms when we compare them. Features that might be used when we compare them. Features that might be used when looking to group organisms could include: 1) Physical structures (e.g anatomy of bones, teeth, organs etc) 2) Biochemistry (e.g protein similarities) 3) Manner of development 4) Behavioural characteristics 5) Similarities in DNA

=__Hierarchies of organisation__= - The smallest unit of amtter, that has all the properties of an element, it cannot be reduced, broken down into any other substance. e.g. Oxygen - 2 or more atoms held together by chemical bonds e.g. H2O - The smallest structural unit of an organism, that is capable of independent functioning and has 1 or more nuclei, in all living things. e.g. Epithelial cell - Cellular organisation, between cells and a organism, cells are not necessarily the same but are together to preform a specific task. e.g. Epithelial tissue - A group of tissue that together preform a specific function. e.g. Brain - A group of organs that work together to preform tasks e.g Nervous system

=**Adaptation**= 1) give an example of an adaptation and how it helps an animal (and it's species) survive Stripes on a tiger, help it sneak up on prey undetected

2)Give 3 examples of: a) Structural adaptations, turtle shell, Meercat claws to dig, vulture beak to break bones b) Behavioural adaptations, sharks getting aggressive when they smell blood, cows anger when something gets near their calf, termites face their nest north

3) Jack Rabbits, Bilbys and Fennec Foxes all live in desert environments. find a picture of each. what structural feature do they obviously share and how does this adaptation help them to survive in their desert habitats

they all have big ears so they can lose heat from pumping blood to there. Their ears have a large surface area and not much hair on them so they heat can escape easily
