Organisms and Populations
No organism lives alone. This chapter in NCERT Class 12 Biology, Chapter 11, studies how individuals, populations and communities respond to temperature, water, light and soil, and explains adaptations, growth curves, age structure, competition, predation, parasitism, commensalism and mutualism. It shows why some species thrive while others decline. You will learn to interpret population graphs, recognise strategies like hibernation and camouflage, and link ecology to conservation of habitats.
