Question

Put the different levels of organization in order from smallest to largest (or in other words, simplest to most complex). Hint: start with “cell” and go as high as you can!

Answer 1

The different levels of biological organization, from smallest (simplest) to largest (most complex), are as follows:

1. **Cell** - The basic unit of life.
2. **Tissue** - A group of similar cells that perform a specific function.
3. **Organ** - A structure composed of different types of tissues working together for a common function.
4. **Organ System** - A group of organs that work together to perform complex functions.
5. **Organism** - An individual living being that can function on its own.
6. **Population** - A group of organisms of the same species living in a specific area.
7. **Community** - Different populations of various species that live and interact in a specific area.
8. **Ecosystem** - A community of living organisms interacting with their physical environment.
9. **Biome** - A larger community characterized by specific climate conditions and similar living organisms.
10. **Biosphere** - The global sum of all ecosystems, representing the zone of life on Earth.

This hierarchy represents the increasing complexity of biological organization.
