Marine Biology is the study of organisms and ecosystems found in marine environments, including microscopic bacteria and complex coral reef systems. It explores the diversity, behavior, and evolution of marine life while examining their interactions with the physical and chemical characteristics of their habitats. As a subdiscipline within Oceanography, Marine Biology specifically focuses on the biological aspects of the ocean. While sharing connections with Science, Environmental Science, and Geography, it delves deeper into the intricate relationships between marine organisms and their environments. By understanding these relationships, researchers can gain insights into broader ecological patterns and processes that shape our planet. Marine Biology encompasses a wide array of topics such as the classification and distribution of marine species, population dynamics, community structure, and the impact of human activities on marine ecosystems. Through the examination of these areas, it contributes significantly to our knowledge of the world's oceans and their crucial role in supporting life on Earth.
