Dear ishritgupta123@gmail.com

Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

Answer to one of your questions is given below:

Some of the concrete examples of the characteristics used for hierarchical classification are:

  1. Nature of the cell- whether the organisms are prokaryotic or eukaryotic in nature.
  2. Cellular nature- whether the organisms are unicellular or multicellular.
  3. Mode of nutrition- whether the organisms are autotrophic or heterophic.
  4. Mode of reproduction- whether the organisms can reproduce sexually or asexually.
  5. Phylogenetic relationship- whether the organisms share a common ancestor or not.

In case of multiple questions within a query, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.
