“10th Class Biology Chapter 16 Quiz: Man and His Environment” is all about the relation between human beings and the environment and how human activities affect ecosystems and natural resources. This chapter is of great importance for MDCAT students as it is necessary to grasp the basic concepts of environmental science in order to understand broad categories of biological and ecological aspects. Our MDCAT Quiz for this chapter enables one to practice and reinforce his knowledge about the environment and its sustainable practices.
The chapter begins by explaining what an ecosystem is: it includes both abiotic or non-living and biotic or living components and their interaction for maintaining ecological balance. Students would learn about energy flow in the ecosystem, beginning from photosynthesis in plants, forming the base of the food chain. The highlights of this chapter are the carbon, nitrogen, and water cycles and how these cycles are vital in sustaining life on Earth. The increasing concern about environmental pollution—air, water, and soil—and how human activities like industrialization and deforestation lead to environmental degradation will also be addressed. This unit will also emphasize the importance of sustainable development, conservation efforts, and environmental protection for the long-term health of the planet.
