Q. The smallest functional ecological unit is _?
Answer:
Ecosystem
Notes: The smallest functional ecological unit is often referred to as an "ecosystem." An ecosystem is a self-contained, interactive system where living organisms (biotic factors) interact with their physical environment (abiotic factors) and with each other. It encompasses a specific area or habitat where organisms coexist and exchange energy and matter through various ecological processes.
Ecosystems can vary in size and complexity, ranging from small-scale microecosystems like a puddle or a tree stump to vast, complex ecosystems like a tropical rainforest or a coral reef. Regardless of their size, ecosystems are characterized by the interconnectedness of their components and the flow of energy and nutrients within them.
Ecosystems play a crucial role in maintaining ecological balance, biodiversity, and the overall health of our planet. They serve as fundamental units for ecological study and conservation efforts, allowing scientists to understand the interactions between organisms and their environment and to address environmental challenges.
