Organism Classification
Learning Objective
I can describe how organisms are classified into a hierarchy based on their characteristics.
Key Concepts
The most basic living level that makes up all of life is the cell, and a group of cells working together forms tissues.
Organs are made up of tissues, and multiple organs working together form an organ system.
A population consists of the same species, while a community includes multiple populations, and an ecosystem includes both biotic and abiotic factors.
