Organism and Populations Organism An organism is an individual living entity that can perform all vital life processes such as growth, metabolism, reproduction, and response to stimuli. Every organism has a specific habitat and niche where it survives and reproduces. Organisms interact continuously with both biotic factors (plants, animals, microbes) and abiotic factors (temperature, water, light, soil). To survive in their environment, organisms show various adaptations like morphological, physiological, and behavioral adaptations. Population A population is a group of individuals of the same species living in a defined geographical area at a particular time and capable of interbreeding. Population has specific characteristics such as population density, natality (birth rate), mortality (death rate), age distribution, and sex ratio, which are not applicable to individual organisms. Population size changes over time due to births, deaths, immigration, and emigration. Growth of population is influenced by environmental factors and follows patterns like exponential growth and logistic growth.
