Final answer:
The levels of organization in the universe, from simplest to most complex, are hydrogen atom, water molecule, skin cell, liver, wolf pack, tropical rainforest, elephant, and planet Earth.
Step-by-step explanation:
The levels of organization in the universe, from simplest to most complex, are as follows:
- Hydrogen atom: The smallest unit of an element.
- Water molecule: A combination of hydrogen and oxygen atoms.
- Skin cell: Basic unit of the skin tissue.
- Liver: An organ made up of cells and tissues performing specific functions.
- Wolf pack: A group of wolves living and working together.
- Tropical rainforest: Complex ecosystem with various plant and animal species.
- Elephant: A living organism made up of multiple systems and organs.
- Planet Earth: The largest encompassing level, consisting of various ecosystems and living organisms.
I placed them in this hierarchy based on their size and complexity. Atoms are the smallest units, followed by molecules, cells, organs, organisms, ecosystems, and finally the entire planet.
