- 1. Population biology is a field of biology that focuses on the study of populations of organisms, including their size, density, distribution, and demographics. It explores how populations change over time in response to various factors such as environmental changes, natural disasters, and human activities. Population biologists examine patterns of birth and death rates, migration, and adaptations within populations to better understand the dynamics and interactions that drive population growth or decline. By studying population biology, scientists gain insights into species conservation, disease transmission, ecosystem stability, and the evolution of populations over generations.
