ORGANISMS AND POPULATION CLASS 12 BIOLOGY NOTES

Organisms and populations are fundamental concepts in ecology that explore the interactions between individual living beings and their environment. An organism refers to any living entity, such as plants, animals, fungi, or microorganisms, that functions independently. Populations, on the other hand, consist of groups of individuals of the same species that live in a specific geographical area and interact with one another. These interactions include competition, predation, cooperation, and reproduction, which influence the population's size, structure, and dynamics. Additionally, populations are affected by abiotic factors like climate and soil, as well as biotic factors like predators and food availability, shaping ecosystems and biodiversity. Understanding these relationships helps in conservation and environmental management.
