Levels of organization (atom-molecule-cell-tissue-organ-organ-system-organism)

Levels of organization

1. atoms 2. molecules 3. organelles 4. cells 5. tissues 6. organs 7. organ systems 8. organisms

Biome

A region of the earth's surface with a specific climate where only certain types of plants and animals live. Ex. Tundra

Organisms

A single living thing that has all of the characteristics of life. Ex. Dog

Organelles

A small part inside a cell that has a specific job to do. Ex. vacuole

Community

All of the different living things (orgamisms) in the same place at the same time. Ex. The white tail deer, oak tree, and gray squirrels in the forest.

Ecosystem

All of the living things (biotic) and the non-living factors (abiotic) in the same place at the same time. Ex. All of the green algae, sunfish, frogs in the water, along with amount of salt and temp of water.

Levels of Biological organization from largest to smallest

Biosphere, Biome, Ecosystem, Community, Population, Organism, Organ System, Organ, Tissue, Cell, Organelle, Molecule, Atom

Organ Systems

Different organs working together to perform a major process in an organism. Ex. Digestive System

Organs

Different tissues working together to form a structure with a specific function. Ex. heart

Tissues

Many cells of the same type working together to perform a function. Ex.

Population

Many organisms of the same type (species) in the same place at the same time. Ex. a herd of Caribou

Cells

The basic unit of structure and function in a living thing. Ex. white blood cell

Biosphere

The part of the earth's surface where living things can be found. Ex. Earth

Atom

The smallest unit of matter that retains all the chemical properties of its respective elements. Proton, Neutron, Electron

Molecules

Two or more atoms bonded together. Ex. water
