Which of the following is NOT abiotic?

Plant

The correct answer is Option (4) – Plant

"Plant" is not abiotic; it is a biotic component of the environment. Biotic factors are living organisms or the products of living organisms that directly or indirectly influence an ecosystem. In contrast, abiotic factors are non-living physical and chemical components of the environment.

Rainfall, soil, and wind are examples of abiotic factors. Rainfall refers to the precipitation of water from the atmosphere, soil comprises the mineral and organic material on the Earth's surface, and wind represents the movement of air molecules in the atmosphere. These factors play crucial roles in shaping ecosystems and influencing the distribution and abundance of biotic organisms within them.
