Chapter 13 – Organisms And Populations
This chapter explains how organisms interact with their environment and how populations of organisms survive and adapt in different ecological conditions. It discusses important ecological concepts such as adaptation, habitat, niche, population density, and population growth. The chapter also explains how environmental factors like temperature, water, light, and soil affect the distribution and survival of organisms. In addition, it covers population interactions such as predation, competition, parasitism, mutualism, and commensalism. Understanding these relationships helps explain how organisms maintain balance in ecosystems and adapt to changing environmental conditions. These concepts are important for both Class 12 board exams and NEET preparation.
