Characteristics of Living Organisms

The ability of living organisms to detect and respond to changes in their environment.

The process by which living organisms maintain a stable internal environment despite external changes.

The process of producing offspring, ensuring the continuation of a species.

The sum of all chemical reactions that occur within a living organism, involving the breakdown and build-up of molecules.

The process by which organisms obtain and use energy from their environment.

The gradual changes in the genetic makeup of a population over time, leading to adaptations.

The organized structure of a living organism, ranging from atoms to organ systems.

The basic unit of life, capable of carrying out all life processes.

A group of similar cells working together to perform a specific function.

A structure made up of different tissues that work together to perform a specific function.

A group of organs that work together to carry out major bodily functions.

A complete living organism made up of multiple organ systems.

A group of individuals of the same species living in the same area.

All the different populations of organisms living and interacting in a particular area.

The part of Earth where all life exists, including all living organisms and their environment.

The process by which organisms take in nutrients from their environment.

The process by which organisms remove waste products produced by their metabolism.

A substance that is made up of two or more elements chemically combined in a fixed ratio.

A specific structure within a cell that performs a particular function.

The smallest unit of an element that retains the properties of that element.

A group of atoms held together by chemical bonds.

The response of plants to light, causing them to bend towards it.

The ability of living organisms to change over time in response to their environment.

The process by which living organisms maintain a relatively stable internal environment.

The process by which organisms take in nutrients from their environment and convert them into usable forms.

The process by which organisms release waste products into their environment.

The organized structure of a living organism from the simplest to the most complex level.

The ability of living organisms to maintain their structure and function over time.

Levels of organization in nature, usually defined by part-whole relationships, with higher levels being composed of lower levels.
