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:
- Nature of the cell- whether the organisms are prokaryotic or eukaryotic in nature.
- Cellular nature- whether the organisms are unicellular or multicellular.
- Mode of nutrition- whether the organisms are autotrophic or heterophic.
- Mode of reproduction- whether the organisms can reproduce sexually or asexually.
- 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.
Regards
Topperlearning Team.
