Solution:

Zoological Parks are protected areas where wild animals are protected by providing conditions as close as possible to natural habitats for public exhibition, for understanding wildlife, recreation and education under ex-situ conservation.
Keys are devices used for identification. They are based on contrasting characters, and separate taxonomic keys are required for each taxonomic category such as family, genus, species. Key is generally analytical in nature and represented by the choice made between two opposite options (contrasting characters). Only one is accepted and the other is rejected.
Herbarium sheets provide common names of the plants.
Taxonomical Aids: Several aids help in taxonomic studies such as herbaria, botanical gardens, museums, zoological parks, monographs, etc. which are helpful in the study of various species of plants, animals and other organisms (that are used in agriculture, forestry, industry) to know bio-resources and biodiversity. Intensive laboratory and field studies are required for the identification of organisms.
