Sort the following taxonomic levels in order from largest to smallest. largest being 1st, smallest being 7th.

1. kingdom
6th
2. phylum
5th
3. class
2nd
4. order
1st
5. family
4th
6. genus
7th
7. species
3rd

The correct order of taxonomic level from in largest to smallest (descending order) is-

Largest---Kingdom- 1st

                Phylum- 2nd

                Class-3rd

                Order-4th

                Family-5th

                Genus-6th

Smallest- Species-7th

Taxonomical classification is a system for classification of organism based on their characteristic features. In this system, organisms are grouped in eight hierarchical categories or taxa mainly-kingdom, phylum, class, order, family, genus and species according to the similar features they share.

Kingdom- The largest taxon on hierarchy is a group of organisms sharing high number of similar features. Nowadays, there are 6 kingdoms: Animalia, Plantae, Fungi, Protista, Archaea, and Bacteria.

After kingdom, phylum,class,order,family,genus and species follows in descending order.

Species- The smallest taxon with group of organisms sharing less similar characters in taxonomical hierarchy and is the most specific level of classification.

Thus, the correct order in descending order is kingdom, phylum, class, order, family, genus and species.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
