Review - Organisms

​

• Organisms are living things.

• Organisms have a life cycle:

  • Be Born, Grow, Reproduce, Die

• Organisms have needs:

Classifying Organisms

• Classify means divide into groups.

• Remember that scientists classify the Earth's components into 4 smaller systems to make Earth easier to study.

• Similarly, ​scientists classify organisms into categories to make the biosphere easier to study.

• ​The categories of organisms are:

  • Producers
