Levels of Biological Organization

Levels of Biological Organization

• Biological organization ranges from molecules and cells to the global biosphere
• This organization builds from simple to increasingly complex levels

Cells

• Cells are the basic unit of life
• They can live and function independently
• All living organisms are made of cells
• Cells have various shapes and sizes
• Some examples of organelles include cilia, lysosomes, vacuoles, cell membranes, and centrioles.

Tissue

• Tissue is a group of similar cells working together
• Different types of tissue perform specific functions in the body
• Examples of tissues include blood, bone, epithelial, cartilage, adipose, nervous, and muscle tissue.

Organs

• Organs are groups of tissues working together
• Each organ performs a specific function
• Organs work together in organ systems
• Examples include the heart and lungs.

Organ Systems

• Organ systems are groups of organs that work together to perform a common function.
• Different systems handle specific body operations
• Examples of organ systems include the nervous, circulatory, respiratory, and digestive systems.

Organism

• An organism is a complete living entity
• Organisms can be unicellular or multicellular
• Examples include animals, plants, and fungi.

Population

• A population is a group of organisms of the same species living in a specific area
• Populations interact with each other and their environment

Community

• A community is a group of interacting populations in a defined area.
• Different populations share resources and interact.

Ecosystem

• An ecosystem consists of an interacting community of organisms and the physical environment they inhabit.
• It includes both living (biotic) and nonliving (abiotic) components.
• Examples include forests, oceans, and deserts

Biosphere

• The biosphere encompasses all living organisms on Earth and their interactions with the planet's physical environment
• It covers the Earth's surface and includes Earth's atmosphere, hydrosphere and lithosphere.
