These MCQs on Zoology enable zoologists and research scholars to analyze their knowledge of the kingdom of animals and its biological processes. Take this free Zoology quiz to reinforce your concepts and learn key subject areas in comparative biology and animal science.

Zoology: It is the science of biology which deals with some classification, physiology, behaviour, development, and evolution of animals. It falls within a very broad scope of subjects from single organisms to entire ecosystems. Other research includes the way animals interact with their surrounding, alteration they experience under changing conditions, and their contribution in maintaining the balance of an ecosystem.

Specializations among the broad field of zoology include ethology or animal behavior, entomology or insects, herpetology or reptiles and amphibians, ornithology or birds, and marine biology or aquatic life. Through all these specializations, zoologists move toward the diversity of animal life and help promote the conservation of threatened species, regulation of wildlife populations, and protection of biodiversity.

Zoology contributes much to human knowledge- both medically and the ecological changes going around the world.
