The term for a biological community and its physical environment interacting together is an ecosystem. Ecosystems comprise living organisms and their abiotic surroundings, ensuring energy flow and nutrient cycling. They are vital for maintaining biodiversity and the overall health of the planet. Ecosystems can vary widely in scale, from small ponds to vast forests or oceans, and they can be influenced by human activities, climate change, and natural disasters. Maintaining healthy ecosystems is essential for providing resources, services, and resilience against environmental changes.
