What is ecosystem? |
Group of interacting species at one place. Group of interbreeding organisms only. Functional unit of nature, where living organisms interact among themselves and also with the surrounding physical environment. Group of living organisms and their interaction between them. |
Functional unit of nature, where living organisms interact among themselves and also with the surrounding physical environment. |
The correct answer is Option (3) – Functional unit of nature, where living organisms interact among themselves and also with the surrounding physical environment. An ecosystem is defined as a functional unit of nature where living organisms (plants, animals, microorganisms) interact not only among themselves but also with the non-living components (air, water, soil, etc.) of their environment. This interaction forms a network of relationships that sustain the ecosystem, enabling the flow of energy, cycling of nutrients, and overall maintenance of life within it. The other options either focus solely on living organisms or lack a comprehensive view that includes interactions with the physical environment. |
