This chapter covers the causes and effects of air, water, soil, radioactive and noise pollution. It explains deforestation and global warming. We will also study the causes of ozone layer depletion and the methods by which we can control it.

Environmental Issues

This chapter explores the causes of biodiversity loss. It discusses the levels, magnitude and patterns of biodiversity. We will learn the importance of conserving biodiversity and the different approaches by which we can conserve it.

Biodiversity and Its Conservation

This chapter sheds light on the types, components, structure and functions of the ecosystem. It explains food chain, food web, ecological pyramid, and biogeochemical cycle. We will also learn the limitations of ecological pyramids.

This chapter discusses the different organizational levels of ecology in detail. It explores the components of the ecosystem. It also briefs on population growth, population interaction and population attributes.

Organisms and Populations

This chapter highlights the applications of biotechnology in agriculture and medicine. It briefs on the benefits of transgenic animals. It also discusses the controversies in India regarding biopiracy and patent.

Biotechnology and Its Application

This chapter discusses the principles of biotechnology in detail. It explains the three basic steps in genetic engineering. It also enhances our knowledge regarding bioreactors and cloning vectors.

Biotechnology - Principles and Processes

In this chapter, we will learn about microbes. We will study the uses of microbes in household products, sewage treatment, and industrial products. It also explains the uses of biogas plant and the process of biogas production.

Microbes in Human Welfare

This chapter explains the processes involved in poultry and farm management. It discusses the steps involved in plant breeding. It discusses the different types of animal husbandry. A brief note on green revolution is given here.
