Final answer:
In biology, the levels of organization range from the atom to the organism. These levels include organelles, cells, tissues, organs, organ systems, populations, communities, ecosystems, and the biosphere.
Step-by-step explanation:
In biology, the levels of organization range from the smallest unit, which is the atom, to the largest unit, which is the organism. In between are organelles, cells, tissues, organs, organ systems, populations, communities, ecosystems, and the biosphere.
For example, atoms combine to form molecules, which then come together to create organelles within cells. Cells are the building blocks of tissues, which make up organs, and organs work together in organ systems to carry out specific functions in an organism.
At the higher levels of organization, populations of the same species interact to form communities, which are part of ecosystems. And finally, all ecosystems together make up the biosphere, which includes all living organisms and their environments on Earth.
