Organisms

Organisms are living things that carry out life processes such as growth, reproduction, and response to their environment. They can be as small as bacteria or as large as whales. All organisms are made up of one or more cells, which function together to keep them alive. They use energy from food or sunlight, adapt to changes, and interact with other living things. In essence, organisms are the basic units of life, capable of maintaining their own existence and evolving over time through natural processes.
