Atoms are building blocks of all things in the world. These atoms come together to create molecules. These molecules can join to create cells, the basic unit of living beings. Cells with similar structures and functions can be brought together to form tissues, and these tissues can form organs which carry out specific tasks. Organs that interact with each other to accomplish specific tasks are organized into organ systems. Several organ systems can help create an organism. Multiple organisms of the same type in the same area are organized into populations. Populations that are in the same area and interact with each other are called a community. Communities can interact with the physical features located in their surrounding area to create an ecosystem. The collection of ecosystems on our earth is called the biosphere.
