Take inorganic materical and make organic matericals.
Inorganic
Does not contain carbon and hydrogen together.
Organic
Does contain carbon and hydrogen together.
Heterotrophic
Organism cannot make its own nutrients and must get it ready made from the environment.
Transport
Materials enter, leave and are distributeds withins organism or cell.
Single-Celled
Organisms exchanges directly with environment.
Multicelled
Organism exchange directly with a circulatory system that travels between cells.
Absorbtion
MAterials taken into an organism.
Circulation
Movement of materials within cell or organism.

-All living and non-living things in an area
-Ex.)Woodland, Pond, Rainforest, and Ocean
-All ecosystems combine to make up the biosphere
Organisms
-An individual living thing
-ex.)bird, rosebuch, bacteria

Combination of parts form a complex organizaiton or "System."
The Celluar Basis of Life
All organisms made of cells
-unicelluar organisms made of cells one celled organism where cells components perform all life functions
-Multicelluar organisms where speciallize cellls work together to perform life functions
Order of Existance
Cell-Tissue-Organ-Organ Systems-Organisms
Form and Function
"Form fits function"
-How something works is related to its structure.
Reproduction & Inheritance
An organism ability to reproduce organisms of there own kind.
Interace w/ the Environment
No organism is completely isolated form the environment
-Organisms conitually inerace w/ the environment

-All organisms require "fuel to carry on life functions
-Fuels:Sugar, protein, fat
Regulation
-the ability of an organism to regulate their internal conditions
-Homeostasis
Adaption
An inherited trait that helps an organisms ablity to survive in the environment.
Natural Selection
Natural environmental conditions determine which trait will be advantageous.
Variation
Onganisms within the population are not exactly alike.
Give a population a better chance to survive in changing environmental conditions.
Evolution
A generation to generation change in the the proportion of different inherited genes in a population.
Biology and Society
The changes in everyday life caused by biology.
Scientific Inquiry
Ask questions about nature and then using obeservaitons or experiments to find possible answers.
