Living World
(mataora)
The living world unit is about living things and how they interact with each other and the environment. Students develop an understanding of the diversity of life and life processes, of where and how life has evolved, of evolution as the link between life processes and ecology, and of the impact of humans on all forms of life.
Biology is the Study of Living Things
LIVING,DEAD AND NON-LIVING
The world is made up of living and non-living things
The main difference between living and non-living things is that a living organism is or was once alive, whereas a non-living thing has never been alive
Non-living is not the same as being dead because non-living things were never alive and therefore cannot die

HOW DO WE CLASSIFY THE LIVING WORLD?THE LINNAEAN(LINNAEUS) SYSTEM
Swedish naturalist and explorer Carolus Linnaeus was the first to frame principles for defining natural genera and species of organisms and to create a uniform system for naming them, known as binomial nomenclature.
ANIMAL CLASSIFICATION
ANIMALS ARE CLASSIFIED INTO TWO MAIN GROUPS: VERTEBRATES (WITH BACKBONE) AND INVERTERBRATES (NO BACKBONE) CLICK ON THIS LINK TO LEARN MORE: http://teachingandlearningresources.co.uk/classification.pdf

THE DICHOTOMOUS KEY
Classification is an important tool used by scientists to show how organisms are different to each other
They are also used to group similar organisms by their characteristics
In order to tell the difference between species or groups of organisms, scientists use a tool called a Classification Key known as the Dichotomous Key
"Dichotomous"means "divided into two parts"
These keys usually consist of a series of questions that have simple answers and can be answered by looking at the specimen
Dichotomous keys are usually represented in one of two ways:
1) As a series of paired statements laid out in a numbered sequence (descriptive representation)
2) As a branching flowchart (diagrammatic representation)

WHAT ARE SPECIALISED CELLS?
-are cells that have a specific structure for a particular function
THE MICROSCOPE
Most cells are to small to be clearly seen by eye and require a microscope to view
Definitions:
Magnification: the number of times the image is enlarged
Resolution: the clarity (how clear) and ability to see detail in
MICROSCOPE PARTS AND FUNCTION
USING A MICROSCOPE SAFELY
PREPARING A SLIDE TO VIEW UNDER THE MICROSCOPE
WHAT IS AN ECOSYSTEM?
SOME EXAMPLES OF ECOSYSTEMS
FEEDING RELATIONSHIPS - FOOD CHAINS (HEI KAI)
ASSSEMBLE FOOD CHAIN LINKS
FOOD WEB (TUKUTUKU KAI)
A food web is the interconnection of food chains in an ecological community. It shows the feeding relationships present in a community
WHAT IS A HABITAT (NOHO)?
- a habitat is the home of an organism or the exact place where an organism lives
- an organism needs food, water, air, space and shelter to survive in its habitat
WHAT ARE ADAPTATIONS (URUTAUNGA)?
Adapations are characteristics, behaviours or features which help an organism to live successfully in its habitat
ADAPTATIONS OF OTHER ANIMALS
