A population is defined as a group of individuals of the same species living in the same geographical area at the same time, capable of interbreeding. Understanding populations is crucial for several reasons: • It allows scientists to study population dynamics, such as birth rates, death rates, and migration, which influence the size and structure of a group. • This knowledge is vital for conservation efforts, helping to manage endangered species and maintain biodiversity. • It also aids in resource management, ensuring sustainable use of natural resources like fish stocks or timber. • For humans, studying population trends helps in urban planning, public health, and allocating resources effectively.
