c) It is necessary to classify organisms because: ... It helps in the identification of living organisms as well as in understanding the diversity of living organisms. Classification helps us to learn about different kinds of plants and animals, their features, similarities and differences.
d) The main criteria for classifying organism into five kingdoms are the complexity of cells structure, body organization, the mode of nutrition, life style, and phylogenetic relationship. This system consists Monera, Protista, Fungi, Plantae, and Animalia.
e) Some characteristics of creepers are as follow:
