In the 9th Class Biology Chapter 3 Quiz Biodiversity, the students learn the wonderful world of living organisms and their diversified characteristics. The chapter focuses on the concept of biodiversity, which means the variety and variability of life on Earth. It is necessary for MDCAT aspirants because it will lay a foundation for topics appearing in the medical and dental college entrance exam. Ecological concepts, including the study of biodiversity, are also practiced through MDCAT Quiz questions. This chapter is very important because it deals with the categorization and preservation of species.
Importance of Biodiversity for MDCAT
Biodiversity is a major topic under the biology section of MDCAT, and it must be understood in different terms viz, genetic, species, and ecosystem diversity. Most questions that are raised by MDCAT Quiz concerning biodiversity ask a student to name various types of ecosystems, why there is an importance of keeping up biodiversity, and threats to the species to become extinct. As you study this chapter, focus on the balance of the ecosystem and interdependence among species in their habitat. Biodiversity is not something to come out and bash in theory exams but has a contribution to real-world medical issues, for example, developing drugs from plant and animal species.
