NEET Biology – Organisms and Populations

Organisms and Populations is an important chapter in Class 12 Biology that explains how living organisms interact with their environment and how populations survive, grow, and adapt to changing conditions. It introduces key ecological concepts related to environmental factors, adaptations, and population dynamics.

This chapter covers abiotic factors such as temperature, water, light, and soil, along with organism adaptations and population attributes. Students will also learn about population growth models, age pyramids, and interactions between species, including mutualism, competition, predation, parasitism, and commensalism.
