Question

Which of the following represents the most correct order of the organization of life from the smallest unit to the largest?

1) atoms ® molecules ® cells ® organisms ® populations ® communities ® ecosystems ® biosphere
2) atoms ® molecules ® cells ® organisms ® communities ® populations ® ecosystems ® biosphere
3) atoms ® molecules ® cells ® organisms ® populations ® ecosystems ® communities ® biosphere
4) communities ® biosphere ® organisms ® ecosystems ® populations ® cells ® molecules ® atoms
5) biosphere ® organisms ® communities ® ecosystems ® populations ® molecules ® cells ® atoms

Answer 1

The correct hierarchy of biological organization from smallest to largest is atoms, molecules, cells, organisms, populations, communities, ecosystems, and finally, the biosphere.

Step-by-step explanation:

The correct order of the organization of life from the smallest unit to the largest is atoms ® molecules ® cells ® organisms ® populations ® communities ® ecosystems ® biosphere. This sequence reflects the hierarchical structure of life, starting with the most fundamental chemical level with atoms and building up through biological complexity to the most inclusive ecological level, the biosphere. Each level of organization builds on the one before it, with atoms combining to form molecules, which in turn make up cells—the building blocks of life. These cells form tissues in multicellular organisms, which form organs and organ systems within organisms. Multiple individual organisms of the same species in an area form populations, which interact with other populations to create communities. Communities and their physical environment make up ecosystems, and all of Earth's ecosystems together constitute the biosphere.
