Answer these 3 questions using the seven Kingdom classifications: a) organism that is beneficial to humans b) two organisms that are harmful to...

The 7 kingdom classification of organisms classifies every organism at 7 different levels, including:

1. Kingdom


2. Phylum


3. Class


4. Order


5. Family


6. Genus


7. Species

In such a classification system, each organism is part of a much, much larger domain (at the top of the classification) and is further sub-classified at each level of this classification system, till we end up with a very particular organism.

For example, dogs are beneficial to human beings and can be classified according to this system as:

Kingdom: Animalis

Phylum: Chordata

Class: Mammalia

Order: Carnivora

Family: Canidae

Genus: Canis

Species: lupus

Here, dogs are part of a kingdom- animalia (along with all the other animals). They are then differentiated at each level of this classification system, till we have only dogs as the species.

A microorganism that is harmful to human beings, Escherichia coli O157:H7 can be similarly classified as:

Kingdom: Bacteria

Phylum: Proteobacteria

Class: Gamma Proteobacteria

Order: Enterobacteriales

Family: Enterobacteriaceae

Genus: Escherichia

Species: Escherichia coli O157:H7

One can similarly find and classify useful as well as harmful organisms. 

Hope this helps.
