Ecology and Environment

In this chapter, we will study the organisms and environment. It states that different organisms interact with the physical environment and form groups such as population. Thus, evolution and ecology are interlinked with each other.

This chapter talks about ecosystems. It is well defined as a system consisting of biotic and abiotic components. The chapter also illustrates the energy flow in an ecosystem and ecological pyramids.

This chapter discusses the concepts of biodiversity and its conservation. Biodiversity is important as it maintains the well-being of human society. It is declining because of species extinction.

In this chapter, we will explore environmental issues such as air pollution, water pollution, soil pollution, and sound pollution. It also describes agrochemicals that are used to maximise crop production.
