An ecosystem is a structural and functional unit of the environment where living organisms interact with one another and with their physical surroundings in a balanced and interdependent manner. It is a complex system that integrates biotic components such as plants, animals, and microorganisms with abiotic components like air, water, soil, light, and minerals. The concept of ecosystem was first introduced by A.G. Tansley in 1935, who emphasized that organisms cannot be studied in isolation but must be understood within the context of their physical and biological environment. Ecosystems can vary in size from a small pond or garden to vast forests, oceans, or even the entire biosphere. They are dynamic systems where the exchange of energy and cycling of nutrients take place continuously, making them the foundation of ecological studies, environmental conservation, and urban development planning. The components of an ecosystem are broadly classified into abiotic and biotic components. Abiotic components are the non-living physical and chemical factors that shape the environment, while biotic components include all living organisms interacting within the system. Both categories are interdependent and together maintain the structure, function, and sustainability of the ecosystem. Abiotic components form the physical foundation of an ecosystem. Solar energy is one of the most vital abiotic factors, as it drives photosynthesis in producers and provides heat that regulates climatic conditions. Light availability determines plant growth, seasonal changes, and diurnal rhythms of organisms. Temperature influences the distribution and activity of species, with different organisms adapted to tropical, temperate, or polar conditions. Water plays a central role, not only as a habitat in aquatic ecosystems but also as a regulator of physiological processes in terrestrial ecosystems. Soil characteristics such as texture, mineral content, pH, and moisture influence vegetation type and, in turn, the diversity of animal communities. The atmosphere provides essential gases like oxygen and carbon dioxide, while nutrients such as nitrogen, phosphorus, and potassium are cycled within ecosystems to maintain productivity. Disturbances such as fire, floods, or urban development also act as abiotic factors that can transform ecosystems and reset ecological succession. Biotic components are categorized into producers, consumers, and decomposers. Producers, primarily green plants and algae, form the base of the ecosystem by capturing solar energy and converting it into chemical energy through photosynthesis. They
