Environmental Biology (Part 1)
Environmental biology is the scientific study of the origins, functions, relationships, interactions, and natural history of living organisms and their populations, communities, and ecosystems in relation to dynamic environmental processes. It integrates principles from ecology, genetics, and conservation biology to understand how organisms adapt to and impact their environments, addressing issues like biodiversity, climate change, and ecosystem health. The Earth’s life support system consists of four main components, collectively known as the ecosphere or biosphere. This refers to the global sum of all ecosystems, encompassing all living organisms and their physical environments on Earth. The ecosphere represents the zone of life on our planet, integrating interactions between the atmosphere, hydrosphere (water bodies), lithosphere (land), and the living organisms within these regions. It is a complex, self-regulating system where energy flows and matter cycles between its componen
