List the levels of biological organization from cell to organism.

Cell, Tissue, Organ, Organ System, Organism

What is the difference between a population and a community?

A population is a group of the same species, while a community includes multiple populations of different species.

I can describe how organisms are classified into a hierarchy based on their characteristics.

1
The most basic living level that makes up all of life is the cell, and a group of cells working together forms tissues.
2
Organs are made up of tissues, and multiple organs working together form an organ system.
3
A population consists of the same species, while a community includes multiple populations, and an ecosystem includes both biotic and abiotic factors.
