Organism Classification

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.
