Hierarchy of Life

Reflection 8/31 – I can explain what is meant by homeostasis and provide an example.

Hierarchy of Life Subatomic Part Tissue Atom Organ Molecule Organ System Macromolecule Organism Organelle Cell Population Community Ecosystem Biome Biosphere

Subatomic Particles Protons, Neutrons, and Electrons!

ATOMS • Smallest unit or particle of matter • Made of Protons, Neutrons, electrons

Levels of Organization Atoms Molecules Macromolecules Organelles Cells Tissues Organ systems Organism Population Community Ecosystem Biome Biosphere Atoms are the simplest form of matter.

Molecules • 2 or more bonded atoms • Forms compounds

Levels of Organization Atoms Molecules Macromolecules Organelles Cells Tissues Organ systems Organism Population Community Ecosystem Biome Biosphere Two or more atoms comprise a molecule.

Macromolecule • Very large molecules – Carbon molecules • Proteins, fats, carbohydrates, nucleic acids • Help build cells

Levels of Organization Atoms Molecules Macromolecules Organelles Cells Tissues Organ systems Organism Population Community Ecosystem Biome Biosphere A macromolecule is a complex of two or more smaller molecules. Most common examples in organisms: proteins, DNA, lipids, and starches.

Organelles • “Tiny organs of the cell” – ER mitochondria, lysosomes, chloroplast, etc • Made of macromolecules

Levels of Organization Atoms Molecules Macromolecules Organelles Cells Tissues Organ systems Organism Population Community Ecosystem Biome Biosphere An organelle is unique functioning part of a cell.

Cell Made of organelles – • Basic “Unit” of life • Red, white blood, bone, nervous, leaf

Levels of Organization Atoms Molecules Macromolecules Organelles Cells Tissues Organ systems Organism Population Community Ecosystem Biome Biosphere Cells are basic unit of all living organisms.

Tissue • Similar cells working together at same function. • Living

Types of Tissues • • Muscle Epitheleal Nervous Connective

Levels of Organization Atoms Molecules Macromolecules Organelles Cells Tissues Organ systems Organism Population Community Ecosystem Biome Biosphere Tissues are groups of cells functioning the same way together.

Organs • Tissues that work together same function • Stomach heart • Lungs brain

Levels of Organization Atoms Molecules Macromolecules Organelles Cells Tissues Organ systems Organism Population Community Ecosystem Biome Biosphere Organs are parts of a body with unique functions.

Systems • Organs that work together same function • Living • Digestive • Respiratory • skeletal

Levels of Organization Atoms Molecules Macromolecules Organelles Cells Tissues Organ systems Organism Population Community Ecosystem Biome Biosphere An organ system is a set of organs and tissues working together as one system.

Organism • Entire living things (organisms) • Usually made of systems • May be a single cell

Levels of Organization Atoms Molecules Macromolecules Organelles Cells Tissues Organ systems Organism Population Community Ecosystem Biome Biosphere All the organ systems functioning together in one body make up an organism.

Population • Same type of organism or species living together • Rattlesnake dolphins, frogs in pond

Species • Same type of organisms that can mate and produce fertile offsprings.

Levels of Organization Atoms Molecules Macromolecules Organelles Cells Tissues Organ systems Organism Population Community Ecosystem Biome Biosphere Members of one species living together in one area make up a population

Community • All populations living together in a specific area. • Populations interact – Competition, symbiotic relationships – mutualism, commensalism, paratism


Levels of Organization Atoms Molecules Macromolecules Organelles Cells Tissues Organ systems Organism Population Community Ecosystem Biome Biosphere Many populations of species living together in one area.

Ecosystem • A biotic (living) community plus the abiotic (nonliving) parts of an environment. Can be large or small

Levels of Organization Atoms Molecules Macromolecules Organelles Cells Tissues Organ systems Organism Population Community Ecosystems is a area with all the communities of Ecosystem organisms interact with each other and their common Biome environment: rivers, mountain ranges, canyon, lake, soil Biosphere types, etc.

Biome • Large areas of the world with similar climates and organisms.

Biosphere • Whole living layer around the globe • All the bioitc and abiotic parts of Earth • Includes abiotic features http: //people. hofstra. edu/geotrans/eng/ch 8 en/conc 8 en/envisys. html
