4. Number of cells: living organisms that are made up of only one cell are classified as unicellular while those with many cells are termed multi cellular.

 5. Reproduction method: living organisms are classified based on whether they reproduce sexually or asexually.

6. Manner of obtaining energy: living organisms that can prouduce their own food are called autotrophs while those that can not produce their own foood are termed heterotrophs. Plants are essentially categorised as autotrophs while animals are described as heterotrophs.</span>
