Levels of Organization Notes Please write TITLE of each slide and the green notes in each box on organizer

ATOMS Smallest part of matter NON-living

Molecules 2 or more bonded atoms Form compounds NON-living

Macromolecule Very large complex molecules (polymers) made of a bunch of smaller molecules that are the same (monomers.) Analogy If you have a pearl necklace. The individual pearls would be the monomer and the necklace would be the polymer. All living things are made up of proteins, fats, carbohydrates, and nucleic acids. NON-living The macromolecules are mainly made of carbon, hydrogen, and oxygen but in different ratios. This gives each compound different properties.

Ex: nucleus, mitochondria Organelles “Tiny organs” Made of macromolecules Non-living Ex: nucleus, mitochondria

Ex: plant cell, skin cell… Made of organelles Basic unit of structure & function LIVING Ex: plant cell, skin cell…

Ex: muscle tissue, nerve tissue The SIMILAR cells working together Living Ex: muscle tissue, nerve tissue

Organs SIMILAR tissues that work together Living Ex: heart, stomach…

Ex: skeletal system, nervous system Organ Systems Organs that work together for similar purpose Living Ex: skeletal system, nervous system

Organism Ex: human, dog Entire living things (organisms) Usually made of systems May be a single cell Living Ex: human, dog

Population Same organisms living together Ex: group of penguins

Ex: penguins, polar bears Community Several populations living together Populations interact Ex: penguins, polar bears

Ecosystem A biotic (living) community and the abiotic (nonliving) features Ex: penguins, polar bears, temperature, & sun

Biome Similar ecosystems on earth together Ex: arctic tundra

Biosphere Whole living layer on Earth Includes abiotic features http://people.hofstra.edu/geotrans/eng/ch8en/conc8en/envisys.html
